bfde644e8a A more general (and simpler!) implementation of r99671. It performs a similar
transform. I.e., if a clean-up eh.selector call dominates the invoke of an
_Unwind_Resume_or_Rethrow, then we convert the eh.selector into a
catch-all. This patch, however, uses the DominatorTree information, and doesn't
go through the whole rigmarole of starting at the eh.exception call, finding the
corresponding URoR and eh.selector calls, and trying to trace through any number
of instruction types to get to them.

fc86c3cfd6 remove support for per-time peak memory tracking, this
isn't used by anyone and is better exposed as a non-per-timer 
thing.  Also, stop including System/Mutex.h in Timer.h

0ea86bc411 various timer fixes: move operator= out of line,
eliminate the per-timer lock (timers should be 
externally locked if needed), the info-output-stream
can never be dbgs(), so drop the check.  Make some
stuff private.

makes calls a little bit more consistent and allows easy removal of the
specializations in the future. Convert all callers to the templated functions.

e27e02b1a4 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."

79c4d820b4 Add NVTBLFrm to represent A8.6.406 VTBL, VTBX Vector Table Lookup Instructions.
These instructions use byte index in a control vector (M:Vm) to lookup byte
values in a table and generate a new vector (D:Vd).  The table is specified via
a list of vectors, which can be:

{Dn}
{Dn D<n+1>}
{Dn D<n+1> D<n+2>}
{Dn D<n+1> D<n+2> D<n+3>}

caa8870fe0 finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
and those derived from them.  These are obnoxious because
they were written as: PatLeaf<(bitconvert).  Not having an
argument was foiling adding better type checking for operand
count matching up with what was required (in this case,
bitconvert always requires an operand!)
