When possible, use "mvn ra, rb" instead of "eor ra, rb, -1" because mvn has a narrow version and eor(i) does not.

This helps it avoid reusing an instruction that doesn't dominate all
of the users, in cases where the original instruction was inserted
before all of the users were known.  This may result in redundant
expansions of sub-expressions that depend on loop-unpredictable values
in some cases, however this isn't very common, and it primarily impacts
IndVarSimplify, so GVN can be expected to clean these up.

This eliminates the need for IndVarSimplify's FixUsesBeforeDefs,
which fixes several bugs.

Add feature flags for AVX and FMA and fix some SSE4A feature flag
initialization problems.

with respect to its loop.

Add x86 support for 'n' inline asm modifier. This will be handled target independently as part of MC work.

the SelectionDAG::getGlobalAddress function properly looks through
aliases to determine thread-localness, but then passes the GV* down
to GlobalAddressSDNode::GlobalAddressSDNode which does not.  Instead
of passing down isTarget, just pass down the predetermined node
opcode.  This fixes some assertions with out of tree changes I'm 
working on.

Currently there is a pattern for the thumb-2 MOV 16-bit immediate instruction. That instruction cannot write the flags so it should use T2I instead of T2sI.
Also, added a pattern for the thumb-2 MOV of shifted immediate since that can encode immediates not encodable by the 16-bit immediate.
