 - outside C++, return undef (behavior is not undefined unless the value is used)
 - in C++, with -fcatch-undefined-behavior, perform an appropriate trap
 - in C++, produce an 'unreachable' (behavior is undefined immediately)

A tweak to the previous commit to ensure that we don't try to use -> on a NULL pointer (should not happen but better be safe than sorry)

<rdar://problem/12413390> Fixing an issue where synthetic ValueObjects do not properly resolve their value

llvm-svn: 165271

enabled after we'd found a few bugs that were caused by shadowed
local variables; the most important issue this turned up was
a common mistake of trying to obtain a mutex lock for the scope
of a code block by doing

        Mutex::Locker(m_map_mutex);

This doesn't assign the lock object to a local variable; it is
a temporary that has its dtor called immediately.  Instead,

        Mutex::Locker locker(m_map_mutex);

does what is intended.  For some reason -Wshadow happened to
highlight these as shadowed variables.

I also fixed a few obivous and easy shadowed variable issues
across the code base but there are a couple dozen more that
should be fixed when someone has a free minute.

reopened as inline, and patch up the name lookup tables to match.

Make sure functions located in user specified text sections (via the
section attribute) are located together with the default text sections.
Otherwise, for large object files, the relocations for call instructions
are more likely to be out of range. This becomes even more likely in the
presence of LTO.

Rename TargetData to DataLayout in DataLayout.cpp. This should fix a build failure from r165249 where the wrong version of the file was submitted.

a) frame setup instructions define the prologue
b) we shouldn't change our location mid-stream

Add a test to make sure that the stack adjustment stays within

crtfastmath.o contains routines to set the floating point flags to a faster,
unsafe mode. Linking it in speeds up code dealing with denormals significantly
(PR14024).

For now this is only enabled on linux where I can test it and crtfastmath.o is
widely available. We may want to provide a similar file with compiler-rt
eventually and/or enable it on other platforms too.

- add tokens to PPCInstrInfo.td and PPCInstr64Bit.td to resolve
"Instruction 'foo' has no tokens" errors during llvm-tblgen
-gen-asm-matcher attempts.  At this time, the added
tokens are "#comment" style rather than the actual mnemonic.  This will
be revisited once the rest of the base asmparser bits get straightened
out for ppc64-elf-linux.

For GNU attributes, instead of reusing attribute source 
location for the scope location, use SourceLocation() since 
GNU attributes don not have scope tokens.
