From Kalle Raiskila:
"the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions:
-in vararg handling, registers are marked to be live, to not confuse the register scavenger
-function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack."

Switch pattern sorting predicate from stable sort -> sort, it
doesn't need to be stable because the patterns are fully ordered.
Add a first level sort predicate that orders patterns in this
order: 1) scalar integer operations 2) scalar floating point
3) vector int 4) vector float. This is a trivial sort on their
top level pattern type so it is nice and transitive. The
benefit of doing this is that simple integer operations are
much more common than insane vector things and isel was trying
to match the big complex vector patterns before the simple
ones because the complexity of the vector operations was much
higher. Since they can't both match, it is best (for compile
time) to try the simple integer ones first.
This cuts down the # failed match attempts on real code by
quite a bit, for example, this reduces backtracks on crafty
(as a random example) from 228285 -> 188369.

Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701).
SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied'

with uninitialized fields, which sometimes caused crashes.
This patch initializes MemoryBlock fields to 0, so that the RWX-failure check
works.

SELinux is in enforcing mode).
