Remove /Wall from LLVM_ENABLE_WARNINGS (it's useless) and promote 4239
to a level 1 warning.

Do not optimize the used bits of the x86 vselect condition operand, when the condition operand is a vector of 1-bit predicates.
This may happen on MIC devices.

llvm-svn: 158168

Fix a bug in FoldSelectOpOp. Bitcast ops may change the number of vector elements, which may disagree with the select condition type.

I falsely assumed that the memory spaces are equal when we reach this
point, they might not be when memory space of one or more is stack or
Unknown. We don't want a region from Heap space alias something with
another memory space.

Match expectations of the new latency API. Cleanup and make the logic consistent.

This patch affects docs only, and includes formatting changes only
(though those include some fixes for broken Doxygen markup that caused
some content to be missing from generated pages).  It avoids generating
many spurious pages such as
http://clang.llvm.org/doxygen/classRepresents.html, but likely not all
yet.

Patch by James Dennett.

Move terminator machine verification to check MachineBasicBlock::instr_iterator instead of MBB::iterator

The integral APSInt value is now stored in a decomposed form and the backing
store for large values is allocated via the ASTContext. This way its not
leaked as TemplateArguments are never destructed when they are allocated in
the ASTContext. Since the integral data is immutable it is now shared between
instances, making copying TemplateArguments a trivial operation.

Currently getting the integral data out of a TemplateArgument requires creating
a new APSInt object. This is cheap when the value is small but can be expensive
if it's not. If this turns out to be an issue a more efficient accessor could
be added.

[Sanitizer] move internal_strdup and internal_memcpy to common runtime. Make internal allocations from TSan runtime call InternalAlloc from common runtime

[Sanitizer] Allocator for internal runtime purposes. Currently it calls libcmalloc, but we might have to make it more low-level in future

Add internal read flags to MachineInstrBuilder and hook them into the MachineOperand flag of the same name

Add a concept of symbolic memory region belonging to heap memory space.
When comparing symbolic regions allocated on the heap, assume that they
do not alias. 

Use symbolic heap region to suppress a common false positive pattern in
the malloc checker, in code that relies on malloc not returning the
memory aliased to other malloc allocations, stack.

put the public function createReaderPECOFF() in the lld namespace and everything else in is own namespace

Before, the note showed the location where you could insert __bridge variants,
but the actual fixit edit came after the cast.

No functionality change.

This was a problem for people who write 'return(result);'

Also fix ARCMT's corresponding code, though there's no test case for this
because implicit casts like this are rejected by the migrator for being
ambiguous, and explicit casts have no problem.
