2f5f90ad3e 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.

85a0a06b18 patch from Frits van Bommel: 
The attached patch fixes IRBuilder and the NoFolder class so that when
NoFolder is used the instructions it generates are treated just like
the ones IRBuilder creates directly (insert into block, assign them a
name and debug info, as applicable).
It does this by
1) having NoFolder return Instruction*s instead of Value*s,
2) having IRBuilder call Insert(Value, Name) on values obtained from
the folder like it does on instructions it creates directly, and
3) adding an Insert(Constant*, const Twine& = "") overload which just
returns the constant so that the other folders shouldn't have any
extra overhead as long as inlining is enabled.

While I was there, I also added some missing (CreateFNeg and various
Create*Cast) methods to NoFolder.

4afa12890f now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate the 
cookie argument to the SourceMgr diagnostic stuff.  This cleanly separates
LLVMContext's inlineasm handler from the sourcemgr error handling 
definition, increasing type safety and cleaning things up.

10d3191cf1 Remove deprecated macro names. Hopefully this will unbreak the

75e2016f02 Remove two uses of the gcc specific 'aligned' attribute. This 
is partly because this attribute caused trouble in the past (the
SmallVector one had to be changed from aligned to aligned(8) due
to causing crashes on i386 for example; in theory the same might
be needed in the Allocator case...).  But it's mostly because
there seems to be no point in special casing gcc here.  Using the
same implementation for all compilers results in better testing.

235859d66c Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also 
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

97816e1bad Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly. 
The problem was that the test for whether a compiler supports it or not was
inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization
and not needed for correctness, so wrongly thinking a compiler doesn't support
it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not
an optimization: getting it wrong is fatal: it needs to be set based on a
configure test not testing the gcc version.  Since dragonegg has moved to a
different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just
remove this macro.
