TblGen/AsmMatcher: Add support for honoring instruction Requires<[]> attributes as part of the matcher.
 - Currently includes a hack to limit ourselves to "In32BitMode" and "In64BitMode", because we don't have the other infrastructure to properly deal with setting SSE, etc. features on X86.

 - Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

portable enough.
 - Downside is we now double dispatch through a stub function, but this isn't
   performance critical.

Add a DAGCombine xform to fold away redundant float->double->float conversions around sqrt instructions.
I am assured by people more knowledgeable than me that there are no rounding issues in eliminating this.

This fixed <rdar://problem/8197504>.

Entirely for testing purposes at the moment.

Still very much under development. Comments and fixes will be forthcoming.

(This commit includes some small tweaks to LiveIntervals & LoopInfo to support the splitter)

PBQP.

Turns out variety is not the spice of life.

Fixed some comparators, added others. All good now.

types.  Use of getType() instead of getRawType() was causing
the type map in constant folding to be updated wrong.
