* Bump version to 0.48.0
* Re-enable `byteorder`'s default features.
The code uses `WriteBytesExt` which depends on the `std` feature being
enabled. So for now, just enable `std`.
Add legalizations for icmp and icmp_imm for i64 and i128 operands for
the narrow legalization set, allowing 32-bit ISAs (like x86-32) to
compare 64-bit integers and all ISAs to compare 128-bit integers.
Fixes: https://github.com/bnjbvr/cranelift-x86/issues/2
This move allows the `IntCC`/`FloatCC` enums to be used in both meta (for predicate matching) and in codegen. To avoid breaking any code dependent on the previous location of condcodes.rs (`cranelift-codegen/src/condcodes.rs`), the module is re-exported under `cranelift_codegen::ir`.
