2511059a16 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>.

8e70968a13 Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop. 
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.

fd8705ab4a Add specializations of addrmode2 that allow differentiating those forms 
which require the use of the shifter-operand. This will be used to split
the ldr/str instructions such that those versions needing the shifter operand
can get a different scheduling itenerary, as in some cases, the use of the
shifter can cause different scheduling than the simpler forms.

56dbefb6d6 lit: Fix a subtle resource usage bug when executing tests using the internal 
shell runner.

We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).

Many thanks to Francois Pichet for the excellent detective work on this.

c14d59589c add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'
