Previous patch fixed one of LLVM buildbots (lld-x86_64-win7).
However, some others have already been failing because of make_unique
compilation error (llvm-clang-x86_64-expensive-checks-win).

This allows llvm-rc to parse user-defined resources (ref:
msdn.microsoft.com/en-us/library/windows/desktop/aa381054.aspx).
These statements either import files, or put the specified raw data in
the resulting resource file.

This allows the ints to be written as integer expressions evaluating to
unsigned 16-bit/32-bit integers.

All the expressions may use the following operators: + - & | ~, and
parentheses. Minus token - can be also unary. There is no precedence of
the operators other than the unary operators binding stronger than their
binary counterparts.

This commit yanks out the repeated sections of code in pruneCandidates into
two lambdas: ShouldSkipCandidate and Prune. This simplifies the logic in
pruneCandidates significantly, and reduces the chance of introducing bugs by
folding all of the shared logic into one place.

Summary:
X86ISelDAGToDAG tries to analyze ANDs compared with 0 to optimize to narrower immediates using subregisters.

I don't think we should be optimizing to 16-bit test instructions. It goes against our normal behavior of promoting i16 operations to i32. It only saves one byte due to the need to add a 0x66 prefix. I think it would also be subject to a length changing prefix penalty in the decoders on Intel CPUs.

LR is an untypical callee saved register in that it is restored into a
different register (PC) and thus does not live-out of the return block.
This case requires the `Restored` flag in CalleeSavedInfo to be cleared.

This fixes a number of cases where this wasn't handled correctly yet.

C11 standard refers to the unsigned counterpart of the type ptrdiff_t 
in the paragraph 7.21.6.1p7 where it defines the format specifier %tu.
In Clang (in PrintfFormatString.cpp, lines 508-510) there is a FIXME for this case,
in particular, Clang didn't diagnose %tu issues at all, i.e.
it didn't emit any warnings on the code printf("%tu", 3.14).
In this diff we add a method getUnsignedPointerDiffType for getting the corresponding type
similarly to how it's already done in the other analogous cases (size_t, ssize_t, ptrdiff_t etc)
and fix -Wformat diagnostics for %tu plus the emitted fix-it as well.

The expensive-checks build bot found a problem with the r314428 commit:
if CC is live after a ATOMIC_CMP_SWAPW instruction, it needs to be
marked as live-in to the block after the loop the pseudo gets expanded
to.  This actually fixes a code-gen bug as well, since if the CC isn't
live, the CR and JLH are merged to a CRJLH which doesn't actually set
the condition code any more.

As reported in https://bugs.llvm.org/show_bug.cgi?id=33235,
a noexcept function was unable to inherit from a nothrow defaulted
constructor. Attribute "nothrow" is supposed to be semantically
identical to noexcept, and in fact, a number of other places in the
code treat them identically.

This patch simply checks the RecordDecl for the correct attribute in
the case where no other exception specifier was set.

Differential Revision: https://reviews.llvm.org/D38209

llvm-svn: 314462

I discovered it was possible to create a 'nothrow' noexcept(false)
function, which is both non-sensical as well as seemingly breaking.

This patch warns if attribute nothrow is used with anything besides "noexcept".

"noexcept(true)" isn't possible, because the noexcept decl isn't parsed until
later.

This setting can be enabled like this at the target level:

(lldb) settings set target.experimental.use-modern-type-lookup true

This causes several new behaviors in the Clang expression parser:

- It completely disables use of ClangASTImporter.  None are created
  at all, and all users of it are now conditionalized on its
  presence.

- It instead constructs a per-expression ExternalASTMerger, which
  exists inside Clang and contains much of the type completion
  logic that hitherto lived in ExternalASTSource,
  ClangExpressionDeclMap, and ClangASTImporter.

- The expression parser uses this Merger as a backend for copying
  and completing types.

- It also constructs a persistent ExternalASTMerger which is
  connected to the Target's persistent AST context.

This is a major chunk of LLDB functionality moved into Clang.  It
can be tested in two ways:

1. For an individual debug session, enable the setting before
   running a target.

2. For the testsuite, change the option to be default-true.  This
   is done in Target.cpp's g_experimental_properties.  The
   testsuite is not yet clean with this, so I have not committed
   that switch.

I have filed a Bugzilla for extending the testsuite to allow
custom settings for all tests:
  https://bugs.llvm.org/show_bug.cgi?id=34771

I have also filed a Bugzilla for fixing the remaining testsuite
failures with this setting enabled:

Attribute nothrow is only allowed on functions, so I added that. Additionally,
it lacks any documentation, so I added some.

{vn} or {v[n]}

{sn} or {s[n]}

{S} , where S is a special register name

In setupEntryBlockAndCallSites in CodeGen/SjLjEHPrepare.cpp,
we fetch and store the actual frame pointer, but on return via
the longjmp intrinsic, it always was restored into the r7 variable.

On windows, the frame pointer should be restored into r11 instead of r7.

On Darwin (where sjlj exception handling is used by default), the frame
pointer is always r7, both in arm and thumb mode, and likewise, on
windows, the frame pointer always is r11.

On linux however, if sjlj exception handling is enabled (which it isn't
by default), libcxxabi and the user code can be built in differing modes
using different registers as frame pointer. Therefore, when restoring
registers on a platform where we don't always use the same register
depending on code mode, restore both r7 and r11.

Summary:
Completion results look much nicer without them.
Informative qualifiers are stored for every method from a base class, even when
calling those methods does not require any qualifiers. For example,
    struct Foo { int foo(); };
    struct Bar : Foo { };
    void test() { Bar(). // Completion item label was 'Foo::foo' before,
                         // but inserted text was simply 'foo'.
                         // We now simply show 'foo' in completion item label.

They effectively cluttered the completion list without providing much value.
