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.
