StructurizeCFG can't handle cases with multiple
returns creating regions with multiple exits.
Create a copy of UnifyFunctionExitNodes that only
unifies exit nodes that skips exit nodes
with uniform branch sources.

r298178 capitalized the fields in `ArgListEntry`. All the official
targets were updated accordingly, but as an experimental target AVR
was missed.

- Avoid explosive growth of the simplification queue by not queuing
expressions that are alredy in it.
- Add an iteration counter and abort after a sufficiently large number
of iterations (assuming that it's a symptom of an infinite loop).

Summary:
The true and false operands for the CMOV are operands 0 and 1.
ARMISelLowering.cpp::computeKnownBits was looking at operands 1 and 2
instead. This can cause CMOV instructions to be incorrectly folded into
BFI if value set by the CMOV is another CMOV, whose known bits are
computed incorrectly.
This patch fixes the issue and adds a test case.

Summary:
1. Support pointer type as function argumnet and return value
2. G_STORE/G_LOAD - set legal action for i8/i16/i32/i64/f32/f64/vec128
3. RegisterBank - support typeless operations like G_STORE/G_LOAD, for scalar use GPR bank.
4. Support instruction selection for G_LOAD/G_STORE

Up until now, vpmovm2 instruction described its destination operand size
by the source operand size. This patch adds new pattern for the vpmovm2
instruction. The node describes new expansion of the destination (from
{128|256} to 512).

This patch introduces X86AsmParser with the ability to handle the aforementioned ops within compound "MS" arithmetical expressions.
Currently - only supported as a stand alone Operand, e.g.:
"TYPE X"
now allowed :
"4 + TYPE X * 128"

[Hexagon] Recognize polynomial-modulo loop idiom again
Regain the ability to recognize loops calculating polynomial modulo
operation. This ability has been lost due to some changes in the
preceding optimizations. Add code to preprocess the IR to a form
that the pattern matching code can recognize.
