Incremental improvement to the handling of the x86 "Jump if rCX Zero"
instruction. Added the 64-bit version "jrcxz" so it is recognized and also
added the checks for incorrect uses of "jcxz" in 64-bit mode and "jrcxz" in
32-bit mode. Still to do is to correctly handle the encoding of the
instruction adding the Address-size override prefix byte, 0x67, when the width
of the count register is not the same as the mode the machine is running in.
Which for example means the encoding of "jecxz" depends if you are assembling
as a 32-bit target or a 64-bit target.

Fixed a bug during widening where we would avoid legalizing a node. When we
replace an OpA with a widened OpB, it is possible to get new uses of OpA due to CSE

new uses of OpA to use OpB.

For NEON vectors with 32- or 64-bit elements, select BUILD_VECTORs and
VECTOR_SHUFFLEs to REG_SEQUENCE instructions. The standard ISD::BUILD_VECTOR
node corresponds closely to REG_SEQUENCE but I couldn't use it here because
its operands do not get legalized. That is pretty awful, but I guess it
makes sense for other targets. Instead, I have added an ARM-specific version
of BUILD_VECTOR that will have its operands properly legalized.

Machine sink could potentially sink instructions into a block where the physical
registers it defines then interfere with an existing preg live range.
For instance, if we had something like these machine instructions:
BB#0
... = imul ... EFLAGS<imp-def,dead>
test ..., EFLAGS<imp-def>
jcc BB#2 EFLAGS<imp-use>
BB#1
... ; fallthrough to BB#2
BB#2
... ; No code that defines EFLAGS
jcc ... EFLAGS<imp-use>
Machine sink will come along, see that imul implicitly defines EFLAGS, but
because it's "dead", it assumes that it can move imul into BB#2. But when it
does, imul's "dead" imp-def of EFLAGS is raised from the dead (a zombie) and
messes up the condition code for the jump (and pretty much anything else which
relies upon it being correct).
The solution is to know which pregs are live going into a basic block. However,
that information isn't calculated at this point. Nor does the LiveVariables pass
take into account non-allocatable physical registers. In lieu of this, we do a
*very* conservative pass through the basic block to determine if a preg is live
coming out of it.
