2a4535353f Revert commit 76707, it was breaking the llvm-gcc build 
on linux platforms.  The binutils assembler does not
recognize the "s" flag, see for example

190d29cb5c Replace the original ad-hoc code for determining whether (v pred w) implies 
(x pred y) with more thorough code that does more complete canonicalization
before resorting to range checks. This helps it find more cases where
the canonicalized expressions match.

2a2501eca4 Fix ocaml tests for 64-bit MacOS systems. LLVM is currently built 
as 32-bit code by default, and if gcc defaults to 64-bit code then ocamlc
requires a -cc "gcc -arch i386" option.  We were hardcoding -cc g++
and throwing away any other compiler options that were determined when
ocamlc was configured and built.

c142755cec Another rewriter bug exposed by recent coalescer changes. ReuseInfo::GetRegForReload() should make sure the "switched" register is in the desired register class. I'm surprised this hasn't caused more failures in the past.

f1c0daa6a7 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

00b05492f1 Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

96f9a917c8 Fix http://llvm.org/bugs/show_bug.cgi?id=4583 
Inline asm instructions may have additional <imp-def,kill> register operands.
These operands are not marked with a flag like the normal asm operands, so we
must not assert that there is a flag.

e507c1afaa Canonicalize bitcasts between types like <1 x i64> and i64 to 
insertelement/extractelement.

I'm not entirely sure this is precisely what we want to do: should we 
prefer bitcast(insertelement) or insertelement(bitcast)?  Similarly. should we 
prefer extractelement(bitcast) or bitcast(extractelement)?
