Chandler Carruth 45c2fb1e69 Undo part of my previous commit to mm_malloc.h, going back to the use of
stdlib.h. There were numerous problems with forward declaring 'malloc' and
'free', but the most important is that these are reserved by POSIX and may be
implemented via a function-like macro.

As suggested by Dale Johannesen, I'm instead guarding the only include of this
in our builtin headers with __STDC_HOSTED__, and I've removed the include of
the header from the test suite. I'll discuss with folks whether we want to have
a hosted section of the test suite or not, and add it (and perhaps other tests)
back there if that's the direction.

Duncan Sands cf4bceba49 Add a rather pointless InstructionSimplify transform, inspired by recent constant
folding improvements: if P points to a type of size zero, turn "gep P, N" into "P".
More generally, if a gep index type has size zero, instcombine could replace the
index with zero, but that is not done here.

the code to not add a "condition code" if it's trap.

Chris Lattner 6ce038082b apply Dan's fix for PR8268 which allows constant folding to handle indexes over
zero sized elements.  This allows us to compile:

Chris Lattner 5957229659 rework some DSE paths to use the newly-public "getPointerDependencyFrom"
method in MemDep instead of inserting an instruction, doing a query,
then removing it.  Neither operation is effectively cached.

destination location of a memcpy/memmove.  I'm not clear about whether
TBAA works on these, so I'm leaving it out for now.  Dan, please revisit
this when convenient.

Francois Pichet 783dd6ece4 Major anonymous union/struct redesign.
A new AST node is introduced:
   def IndirectField : DDecl<Value>;
IndirectFields are injected into the anonymous's parent scope and chain back to
the original field. Name lookup for anonymous entities now result in an
IndirectFieldDecl instead of a FieldDecl.
There is no functionality change, the code generated should be the same.

Chris Lattner 58f9f58716 Implement PR8644: forwarding a memcpy value to a byval,
allowing the memcpy to be eliminated.

Unfortunately, the requirements on byval's without explicit 
alignment are really weak and impossible to predict in the 
mid-level optimizer, so this doesn't kick in much with current
frontends.  The fix is to change clang to set alignment on all
byval arguments.
