This commit bumps Cranelift to 0.49.0 and target-lexicon to 0.9.0 to fix the failing build to due an updated faerie crate that violated semver with an updated 0.9.0 target-lexicon dependency. Fixes #491.
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
