020e5987d3 Use little-endian ordering for CLIF vconst immediate 
Examining wasm-objdump revealed that it stores SIMD constants in little-endian order, e.g.:

000071 func[2] <test_const>:
 000072: fd 02 01 00 00 00 02 00 00 | v128.const 0x00000001 0x00000002 0x00000003 0x00000004
 00007b: 00 03 00 00 00 04 00 00 00 |
 000084: fd 0d 03                   | i32x4.extract_lane 3
 000087: 0b                         | end

This change avoids confusion by making the CLIF representation use little-endian order as well.

ff3c44385c Add test run to cranelift-filetests to allow executing CLIF (#890) 
* Add ability to run CLIF IR using `clif-util run [-v] {file}` and add `test run` to cranelift-filetests to allow executing CLIF

This re-factors the compile/execute parts to a FunctionRunner that is shared between cranelift-filetests and clif-util. CLIF can be now be run using `clif-util run` as well as during `clif-util test` for files with a `test run` header. As before, only functions suffixed with a `run` comment are executed. The `run: fn(...) == ...` expression syntax is left for a subsequent change.

036b9aea94 [codegen] Rename and explicit usage of replace_with_alias; 
It can actually only replace one result; don't try to make it generic
yet, since there's no point in doing so right now, and make it do the
dumb thing so it's not surprising to use.

Uses cross-crate documentation links so that rustdoc does the hard work
of making relative links for us.

627ba24b59 Simplify jump table instructions and add missing conversion; 
This makes non-legalized jump table instructions operate on operands with
pointer-sized types. This means we need to extend smaller types into the
pointer-sized operand, when the two don't match.

9b97ddf29a Enable basic block checks through a feature. (#856) 
This allows prefixing BB-specific code with "#[cfg(feature = "basic-blocks")]",
which avoids having to reference an environment variable across the codebase.

The easiest way to enable the feature locally is to add the arguments
'features = ["basic-blocks"]' to the workspace Cargo.toml, where it defines
the cranelift-codegen dependency.
