a31336996c Add support for some packed multiplication for new x64 backend 
Adds support for i32x4, and i16x8 and lowering for pmuludq in
preperation for i64x2.

dd6ba5f9d7 Lower packed integer add instructions (v128) 
Adds lowering support for packed integer add instructions and helper
function for determining if a type for an instruction indicates it is
packed.

4cb36afd7b machinst x64: refactor to use types::[type] everywhere 
This change is a pure refactoring--no change to functionality. It removes `use crate::ir::types::*` imports and uses instead `types::I32`, e.g., throughout the x64 code. Though it increases code verbosity, this change makes it more clear where the type identifiers come from (they are generated by `cranelif-codegen-meta` so without a prefix it is difficult to find their origin), avoids IDE confusion (e.g. CLion flags the un-prefixed identifiers as errors), and avoids importing unwanted identifiers into the namespace.

8cfff26957 machinst x64: implement floating point comparisons 
Note that this fixes an encoding issue in which the packed single and packed double prefixes were flipped.

999e04a2c4 machinst x64: refactor imports to use rustfmt convention 
This change is a pure refactoring--no change to functionality. It removes newlines between the `use ...` statements in the x64 backend so that rustfmt can format them according to its convention. I noticed some files had followed a manual convention but subsequent additions did not seem to fit; this change fixes that and lightly coalesces some of the occurrences of `use a::b; use a::c;` into `use::{b, c}`.

999fa00d6a machinst x64: add loading of inline 128-bit constants 
Eventually the `load + jmp + constant` pattern should be replaced with just `load` once constant pools are more tightly integrated.

7f109a5198 machinst x64: use a sign-extension when loading jump table offsets; 
The jump table offset that's loaded out of the jump table could be
signed (if it's an offset to before the jump table itself), so we should
use a signed extension there, not an unsigned extension.

de4923356a machinst x64: fix fcmp comparison for NotEqual; 
We have to emit both checks against the parity bit (for unordered) and
non-equality bit (for equality), otherwise this returns false when
comparing NaN against itself.
