Also, one binary search is enough.

Extend the r107852 optimization which turns some fp compare to code sequence using only i32 operations. It now optimize some f64 compares when fp compare is exceptionally slow (e.g. cortex-a8). It also catches comparison against 0.0.

bool-to-pointer conversion that occurs withit EXPECT_EQ.

by a return that returns a constant, while elsewhere in the function
another return instruction returns a different constant.  This is a
special case of accumulator recursion, so just generalize the existing
logic a bit.

with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)

this ordering is now consistent with InvokeInst

this commit only flips the switch,
functionally it is equivalent to
r101465

I intend to commit several cleanups after a few
days of soak period

This fixes the himenobmtxpa miscompilation on ARM.

The PostRA scheduler got confused by the double memoperand and hoisted a stack
slot load above a store to the same slot.

Move some SIMD fragment code into X86InstrFragmentsSIMD so that the
utility classes can be used from multiple files.  This will aid
transitioning to a new refactored x86 SIMD specification.

instructions already have implicit defs of LR.  The comment suggests that
this is intended to fix something like pr6111, but it doesn't really do
that either.
