since none of them use it.  With this, we now only run 
domfrontier (an N^2 analysis) 3 times at clang -O3: once for 
"early" per-function cleanup, once at the start of the
per-function pipeline to support SRoA, and once late because
the EHPrepare class uses it.

EHPrepare needs to stop using it, this is silly and wasteful.

of the pass though.

times.  This patch causes llc and llvm-mc (which both default to
verbose-asm) to print out comments after a few common shuffle 
instructions which indicates the shuffle mask, e.g.:

	insertps	$113, %xmm3, %xmm0     ## xmm0 = zero,xmm0[1,2],xmm3[1]
	unpcklps	%xmm1, %xmm0    ## xmm0 = xmm0[0],xmm1[0],xmm0[1],xmm1[1]
	pshufd	$1, %xmm1, %xmm1        ## xmm1 = xmm1[1,0,0,0]

This is carefully factored to keep the information extraction (of the
shuffle mask) separate from the printing logic.  I plan to move the
extraction part out somewhere else at some point for other parts of
the x86 backend that want to introspect on the behavior of shuffles.
