Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.

Specify an additional fixed bit in the Thumb2 SSAT encoding to prevent the decoder from emitting gibberish for this invalid encoding.

Fix a typo in the bitcode reader in the handling of atomic stores.  Reported by David Meyer on llvmdev.

For instance:

template <class T> void E() {};
class F {};

void test() {
 ::E<::F>();
 E<::F>();
}

Gives the following error messages:

error: found '<::' after a template name which forms the
     digraph '<:' (aka '[') and a ':', did you mean '< ::'?
 ::E<::F>();
    ^~~
    < ::
error: expected expression
 E<::F>();
    ^
error: expected ']'
note: to match this '['
 E<::F>();

This patch adds the digraph fix-it check right before the name lookup,
moves the shared checking code to a new function, and adds new
tests to catch future regressions.

We were failing to set source locations and ranges in isUnusedResultAWarning
for CXXOperatorCallExprs, leading to an "expression result unused" warning
with absolutely no context if the expression was inside a macro.

For example, 'ldrb r9, [sp]!' is odd, but valid.

Report missing template arguments more helpfully by supplying the name

Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO.

- It can take FunctionStarts from a binary to find entry points more accurately.
- Symbol offsets in executables are correct now.

Chris Jefferson noted that vector iterator ownership can be transferred from source to target under move construction and move assignment.  This commit makes that happen for debug mode.

Do not use builtin includes if -fms-compatibility is specified. Some MSVC header files have the same name as clang's builtins, this creates clash.

llvm-svn: 140009

Move the "jump bypasses variable initialization" error -> warning downgrade from -fms-extensions to -fms-compatibility.

llvm-svn: 140008

In Microsoft mode(-fms-compatibility), prefer an integral conversion to a floating-to-integral conversion if the integral conversion is between types of the same size.

For example:
 void f(float);
 void f(int);
 int main {
    long a;
    f(a);
 }
Here, MSVC will call f(int) instead of generating a compile error as clang will do in standard mode.
This fixes a few errors when parsing MFC code with clang.
