This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.

I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.

Before:
  [pboard setData:[NSData dataWithBytes:&button
                                 length:sizeof(button)]
          forType:kBookmarkButtonDragType];
After:
  [pboard setData:[NSData dataWithBytes:&button length:sizeof(button)]
          forType:kBookmarkButtonDragType];

My previous attempt was extremely deficient, allowing more volatiles
to be introduced and not even checking all of the ones that are
present.

This attempt doesn't try to keep track of the values stored or offsets
within particular objects, just that the correct objects are accessed
in a correctly volatile manner throughout.

Also, remove CLANG_BUILD_TESTS option. It won't have consistent behavior
between standalone and non-standalone builds, so I'm not going to bother
hooking it up for standalone builds. LLVM_BUILD_TESTS will continue to
control unit test inclusion in the "all" target in non-standalone builds.

Finally, fix the default value of CLANG_INCLUDE_TESTS, which was being set
to the boolean value of "LLVM_INCLUDE_TESTS", i.e. OFF, rather than actually
reading the variable ${LLVM_INCLUDE_TESTS}! If you picked up my earlier
commit, YOU WILL HAVE TO MANUALLY SET THIS OPTION BACK ON. My apologies!

Part two of r174691 (allow the unit tests to be built in standalone mode).

Attribute references are of this form:

  define void @foo() #0 #1 #2 { ... }

Parse them for function attributes. If there's more than one reference, then
they are merged together.

allowed size for the instruction. This code uses RegScavenger to fix this.
We sometimes need 2 registers for Mips16 so we must handle things
differently than how register scavenger is normally used.

(lldb) b *0x1234

You can still of course just specify an address:

(lldb) b 0x1234

Also now we accept the '&' before function names to indicate to not to skip the function prologue like GDB supports. To see how this works:

(lldb) settings set interpreter.expand-regex-aliases 1
(lldb) b &main
breakpoint set --name 'main' --skip-prologue=0
Breakpoint 1: where = a.out`main at main.c:20, address = 0x0000000100000b60
(lldb) b main
breakpoint set --name 'main'
Breakpoint 2: where = a.out`main + 54 at main.c:21, address = 0x0000000100000b96

a module for this file, when running on a content-addressible filesystem.

This reverts commit 3854a5d90fee52af1065edbed34521fff6cdc18d.

This causes a clang unit test to hang: vtable-available-externally.cpp.

The reason this is not enabled by default is because there is no way for
Clang to guarantee that the LLVM unit testing infrastruture has been built.
However, if it /has/ been built, there's no reason why the standalone Clang
build can't use it!

This should have no effect on existing builds -- in a combined build the
value of the CLANG_INCLUDE_TESTS option defaults to the LLVM equivalent,
and in a standalone build it defaults to off.

we annotate properly when there is an attribute and not skip type specs
if the attribute is after the declaration.

ParseFnAttributeValuePairs. So just use that instead.

overloads of a name by claiming that there are no lookup results for that name
in modules while loading the names from the module. Lookups in deserialization
really don't want to find names which they themselves are in the process of
introducing. This also has the pleasant side-effect of automatically caching
PCH lookups which found no names.

The runtime here is still quadratic in the number of overloads, but the
constant is lower.

The malloc checker will now catch the case when a previously malloc'ed
region is freed, but the pointer passed to free does not point to the
start of the allocated memory. For example:

int *p1 = malloc(sizeof(int));
p1++;
free(p1); // warn

From the "memory.LeakPtrValChanged enhancement to unix.Malloc" entry
in the list of potential checkers.

The checkPointerEscape callback previously did not specify how a
pointer escaped. This change includes an enum which describes the
different ways a pointer may escape. This enum is passed to the
checkPointerEscape callback when a pointer escapes. If the escape
is due to a function call, the call is passed. This changes
previous behavior where the call is passed as NULL if the escape
was due to indirectly invalidating the region the pointer referenced.

This patch makes sure that we do not reinitialize static globals when
the function is called more than once along a path. The motivation is
code with initialization patterns that rely on 2 static variables, where
one of them has an initializer while the other does not. Currently, we
reset the static variables with initializers on every visit to the
function along a path.
