Enhance clang_getCXTUResourceUsage() to report how much memory is used by SourceManager's memory buffers.

llvm-svn: 130433

Add MemoryBuffer::getBufferKind() to report whether a memory buffer uses malloc'ed or mmap'ed memory.  This is for performance analysis.

Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing.

Use StringRef::substr() and unbounded StringRef::compare() instead of bounded version of StringRef::compare() because bounded version of StringRef::compare() is going to be removed.

Make the top-level driver ignore -fobjc-default-synthesize-properties while this feature undergoes more review and development.  This is still available as a -cc1 option for testing.

Eliminates an assert in the strncpy/strncat checker caused by not validating a cast was successful. If the value of an argument was unknown, the cast would result in a NULL pointer which was later being dereferenced.

This fixes Bugzilla #9806.

  %x1 = load i32* %0, align 4
  %1 = icmp eq i32 %x1, 1179403647
  br i1 %1, label %if.then, label %if.end

instead of doing lots of loads and branches.  May the FreeBSD bootloader

non-CVR qualifiers as well as CVR qualifiers. For example, don't allow
a reference to an integer in address space 1 to bind to an integer in
address space 2.

Fix a bug in tblgen that caused incorrect encodings on instructions that specified operands with "bit" instead of "bits<1>".
Unfortunately, my only testcase for this is fragile, and the ARM AsmParser can't round trip the instruction in question.

Add command line option to print debug info in human readable form as comment in llvm IR output. This, i.e -enable-debug-info-comment,  is very useful if you want to easily find out which optimization pass is losing line number information.

as a keyword for the __is_signed type trait. Cope with this conflict
via some hackish recovery: if we see a declaration of the form

 static const bool __is_signed

then we stop treating __is_signed as a keyword and instead treat it as
an identifier. It's ugly, but it's better than making the __is_signed
type trait conditional on some language flag. Fixes PR9804.

a bit more sinister as the memset doesn't do what the constructor does.
There seems to be a cleaner solution than a cast here though, instead we
can point the memset destination into the union its actually trying to
clear.

An alternative is to point to the Untyped member of this union. Review
appreciated, and if that is cleaner I'm happy to switch. All of these
should be functionally equivalent to the original code.
