Recommit r158407: Allow SROA to look at a vector type and see if the offset is out of range to be replaced with a scalar access.  Now with additional fix and test for indexing into a vector inside a struct

consideration the global base register slot on the stack when computing the
stack size.

Long-branches need access to the global base register to get the destination

This is the first of a series of patches which implements long branch expansion
for MIPS.

delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen.

This change, along with the fix in r158154, enables machine verification
to be run after delay slot filling.

(add v0, (add v1, abs_lo(tjt))) => (add (add v0, v1), abs_lo(tjt))

"tjt" is a TargetJumpTable node.

use a numeric constant for now so that we don't require an unreleased

out.

since then the entire expression must equal zero (similarly for other operations
with an absorbing element).  With this in place a bunch of reassociate code for
handling constants is dead since it is all taken care of when linearizing.  No
intended functionality change.

Fix intrinsics for XOP frczss/sd instructions. These instructions only take one source register and zero the upper bits of the destination rather than preserving them.

This patch extends FoldBranchToCommonDest to fold unconditional branches.
For unconditional branches, we fold them if it is easy to update the phi nodes 
in the common successors.
