38428e1fbb Expand modules instantiated in instantiate-wasm-smith 
This commit uses the new `MaybeInvalidModule` type in `wasm-smith` to
try to explore more points in the fuzz target space in the
`instantiate-maybe-invalid` fuzz target. The goal here is to use the raw
fuzz input as the body of a function to stress the validator/decoder a
bit more, and try to get inputs we might not otherwise generate.

e92f949663 AArch64: Introduce an enum for ternary integer operations 
This commit performs a small cleanup in the AArch64 backend - after
the MAdd and MSub variants have been extracted, the ALUOp enum is
used purely for binary integer operations.

Also, Inst::Mov has been renamed to Inst::Mov64 for consistency.

a7f7c23bf9 machinst aarch64: in baldrdash, allow returning only one value across register classes; 
Baldrdash's API requires that there is at most one result in a register,
across all the possible register classes: in particular, it's not
possible to return an i64 value in a register while returning an v128
value in another register.

This patch adds a notion of "remaining register values", so this is
properly taking into account when choosing whether a return value may be
put into a register or not.

91dac9c7e8 wiggle: witx paths use shell expansion 
instead of always being relative to CARGO_MANIFEST_DIR, each use site is
responsible for either putting that variable or another one (set by a
build.rs) at the start of witx paths.
