Add x86 encoding for SIMD icmp eq
...
Also adds a predicate for matching the `eq` IntCC code (TODO this should be replaced by something more general)

[codegen] reintroduce support for carry and borrow instructions in RI… ( #1005 )
...
Reintroduce support for iadd carry variants and isub borrow variants for
RISC ISAs which had been removed in
https://github.com/CraneStation/cranelift/pull/961 and
https://github.com/CraneStation/cranelift/pull/962 because of the lack
of a proper flags register in RISC architectures.

Avoid extra register movement when lowering the x86 extractlane of a float vector
...
This commit is based on the assumption that floats are already stored in XMM registers in x86. When extracting a lane, cranelift was moving the float to a regular register and back to an XMM register; this change avoids this by shuffling the float value to the lowest bits of the XMM register. It also assumes that the upper bits can be left as is (instead of zeroing them out).

Use raw_bitcast when legalizing splat
...
raw_bitcast matches the intent of this legalization more clearly (to simply change the CLIF type without changing any bits) and the additional null encodings added are necessary for later instructions

Avoid unnecessary lane calculations in codegen code
...
This refactor moves the calculation of the number of lanes to code closer to where the Instruction/BoundInstruction is bound.
