Lower X%C into X/C+stuff. This allows the 'division by a constant' logic to
...
apply to rems as well as divs. This fixes PR945 and speeds up ReedSolomon
from 14.57s to 10.90s (which is now faster than gcc).
It compiles CodeGen/X86/rem.ll into:
_test1:
subl $4, %esp
movl %esi, (%esp)
movl $2155905153, %ecx
movl 8(%esp), %esi

_test2:

sarl $31, %ecx

imull $255, %edx, %eax
subl %eax, %esi
movl %esi, %eax
movl (%esp), %esi
addl $4, %esp
ret
instead of div/idiv instructions.

with ParseBytecodeFile used to leak both a ModuleProvider (and related

Prior load folding check on chain operand was too strict. It requires the
...
chain operand to point to the load being folded. Now we relax this, traversing
up the chain, if it doesn't reach the load, then it's ok. We will create a
TokenFactor (of all the chain operands and the load's chain) to capture all
the control flow dependencies.
