The shifts clippy objects to are the point. These are instruction ENCODERS:
every field is written at its ISA position, so `(((vb >> 5) & 0x3) << 0)`
sits in a column with << 11, << 16, << 21 and reads straight against the
manual's field table, and a trailing `| 0` says 'the low field is zero
here', which is information.
Reduced to what clippy wants, the encodings stop being checkable by eye
against the ISA -- and eye-checkability is all a golden GENERATOR has. There
is nothing else to verify it against.

Three tests failed on the extracted tree for a reason that was not a port
defect: disasm_goldens.rs resolves its fixtures through a relative path to
xenia-cpu/tests/golden/, and I had copied the test without the data.
The fixtures (base + extended mnemonics, VMX128 registers) and the generator
test now live in sylpheed-ppc, and the shim test in sylpheed-xexdb points at
them. serde/serde_json become dev-dependencies of sylpheed-ppc, which the
fixtures need and the library does not.

rustfmt, then clippy -D warnings across the three new crates. Mechanical,
except three decisions that are stated rather than silently allowed:
* lzx.rs gets file-scoped needless_range_loop/explicit_counter_loop allows.
Index arithmetic IS the algorithm -- LZX is defined over symbol indices,
Huffman slots and window positions, and a decompressor that is merely
idiomatic is worth nothing if it is not bit-exact.
* sylpheed-xexdb gets crate-scoped allows for needless_range_loop (nine
sites index reg[r] where r is the PowerPC register number -- the index is
the meaning), too_many_arguments and type_complexity. This code arrived
whole from a retired repository; a refactor here would be an unreviewed
edit dressed as a lint fix.
* Everything else clippy asked for is FIXED, including all 14 doc-indent
sites, the let-else, and a Prepared type alias in the binary.
