cacdc4d65a Remove ICmpInst::isSignedPredicate which was a reimplementation 
CmpInst::isSigned.

a16e115bd4 Sink isTrueWhenEqual from ICmpInst to CmpInst. Add a matching isFalseWhenEqual 
which is equal to !isTrueWhenEqual for ints but not for floats.

e8998896f5 Auto-upgrade free instructions to calls to the builtin free function. 
Update all analysis passes and transforms to treat free calls just like FreeInst.
Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised.

7137e5f065 Incorporate various suggestions Chris gave during metadata review. 
- i < getNumElements()  instead of getNumElements() > i
- Make setParent() private
- Fix use of resizeOperands
- Reset HasMetadata bit after removing all metadata attached to an instruction
- Efficient use of iterators

4f6c397742 Fix test/Bindings/Ocaml/vmcore.ml. When IRBuilder::CreateMalloc was removed, 
LLVMBuildMalloc was reimplemented but with the bug that it didn't insert the
resulting instruction.

2c890dc2b4 Teach vm core to more aggressively fold 'trunc' constantexprs, 
allowing it to simplify the crazy constantexprs in the testcases
down to something sensible.  This allows -std-compile-opts to
completely "devirtualize" the pointers to member functions in
the testcase from PR5176.

4d7283f82c Autoupgrade malloc insts to malloc calls. 
Update testcases that rely on malloc insts being present.

Also prematurely remove MallocInst handling from IndMemRemoval and RaiseAllocations to help pass tests in this incremental step.

4fcf6123dd I don't see any point in having both eh.selector.i32 and eh.selector.i64, 
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector.
Likewise for eh.typeid.for.  This aligns us with gcc, which always uses a
32 bit value for the selector on all platforms.  My understanding is that
the register allocator used to assert if the selector intrinsic size didn't
match the pointer size, and this was the reason for introducing the two
variants.  However my testing shows that this is no longer the case (I
fixed some bugs in selector lowering yesterday, and some more today in the
fastisel path; these might have caused the original problems).

7db511a23e Add an "msasm" flag to inline asm as suggested in PR 5125. 
A little ugliness is accepted to keep the binary file format
compatible.  No functional change yet.

729589a539 Copy metadata when value is RAUW'd. It is debatable whether this is the right approach for custom metadata data in general. However, right now the only custom data user, "dbg", expects this behavior while FE is constructing llvm IR with debug info.

68e044e81a Add a form of addPreserved which takes a string argument, to allow passes 
to declare that they preserve other passes without needing to pull in
additional header file or library dependencies. Convert MachineFunctionPass
and CodeGenLICM to make use of this.

a3cf123e86 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.
