This PR updates Cranelift to use the new version of regalloc.rs
(bytecodealliance/regalloc.rs#55) that provides dense vreg->rreg maps to
themap_reg()function for each instruction, rather than the earlier
hashmap-based approach.In one test (regex-rs.wasm), this PR results in a 15% reduction in
memory allocations (1245MB -> 1060MB) as measured by DHAT onclif-util wasmruns.Requires regalloc.rs release and dependency version-bump; CI will be red
until this happens.<!--
