Fix a significant recent(?) regression. StackSlotColoring no longer did anything
...
because LiveStackAnalysis was not preserved by VirtRegWriter. This caused
big stack usage regression in some cases.

ARM: Use a dedicated intrinsic for vector bitwise select.
...
The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

Ignore PHI-defs for -new-coalescer interference checks.
...
A PHI can't create interference on its own. If two live ranges interfere
at a PHI, they must also interfere when leaving one of the PHI
predecessors.

Extend -new-coalescer SSA update to handle mapped values as well.
...
The old-fashioned many-to-one value mapping doesn't always work when
merging vector lanes. A value can map to multiple different values, and
it can even be necessary to insert new PHIs.
When a value number is defined by a copy from a value number that
required SSa update, include the live range of the copied value number
in the SSA update as well. It is not necessarily a copy of the original
value number any longer.

SinkThenElseCodeToEnd. When END block has only two predecessors and each
predecessor terminates with unconditional branches, we compare instructions in
IF and ELSE blocks backwards and check whether we can sink the common
instructions down.
