Revert r151879, r151880, "PR12145: Avoid emitting loads of constexpr variables in contexts where there" and "Fix buildbot: make this test less dependent on the value names in the produced IR."

They broke bootstrap.

No, really, make doesn't work with spaces.

This could probably be made a lot smarter, but this is a common case and doesn't require LVI to scan a lot
of code. With this change CVP can optimize away the "shift == 0" case in Hashing.h that only gets hit when
"shift" is in a range not containing 0.

llvm-svn: 151919

Hashing: microoptimize a truncate on 64 bit away. This currently blocks dead code eliminating the conditional.

The optimizer should handle this eventually, but currently LVI isn't really designed for this kind of stuff.

folks who know something about PPC tell me that the byte swap is crazy
fast and without this the bit mixture would actually be different. It
might not be worse, but I've not measured it and so I'd rather not trust
it. This way, the algorithm is identical on both endianness hosts. I'll
look into any performance issues etc stemming from this.

llvm-svn: 151892

just ensure that the number of bytes in the pair is the sum of the bytes
in each side of the pair. As long as thats true, there are no extra
bytes that might be padding.

Also add a few tests that previously would have slipped through the
checking. The more accurate checking mechanism catches these and ensures
they are handled conservatively correctly.

Thanks to Duncan for prodding me to do this right and more simply.

try to define C++ keywords as typedefs (fixed in Solaris 11).

llvm-svn: 151890

Unconditionally define __C99FEATURES__ when using C++ on Solaris.  This is a
(hopefully temporary) work around for libc++ exposing C99-but-not-C++98
features in C++98 mode.

This change replaces getTypeStoreSize with getTypeAllocSize in AddressSanitizer
instrumentation for stack allocations.

One case where old behaviour produced undesired results is an optimization in
InstCombine pass (PromoteCastOfAllocation), which can replace  alloca(T) with
alloca(S), where S has the same AllocSize, but a smaller StoreSize. Another
case is memcpy(long double => long double), where ASan will poison bytes 10-15
of a stack-allocated long double (StoreSize  10, AllocSize 16,
sizeof(long double) = 16).

See http://llvm.org/bugs/show_bug.cgi?id=12047 for more context.
