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.

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.

2632848491 Relocation of DW_OP_{bra, skip} instructions (#2143) 
The fundamental problem is that the target distance of jump-like operations may change in the DWARF expression translation process. Intervening DW_OP_deref will expand to about 10 bytes, for example.

So the jumps must be relocated. We approach this task by inserting artificial LandingPad markers (new CompiledExpressionParts constructors) into the parsed vector at actual Jump targets.

LandingPads are identified by JumpTargetMarker tokens which are generated on the fly.

Additionally we now parse the Jump instructions. These also get their corresponding JumpTargetMarker token.

We bail in two situations:

    frame_base is too complicated (i.e. itself contains Jump)
    some jump distance in the original expression is fishy.

6513e90914 use the obvious DW_OP_const4u for 0xffff_ffff (#2154) 
No point in resorting to LEB128 encoding for such constants,
using the native `u32` is faster and more compact.

Adds `write_u32` method to facilitate this.
