SIMD loads/stores checked bit 0x20 of the align immediate to detect a
following memory index, unlike scalar mem ops which use 0x40 per the
multi-memory encoding. This caused the memidx byte to be misparsed as
the next immediate (e.g. offset).
Update both SIMD sites (v128 load/store and lane variants) to check and
clear 0x40, then read LEB128<u32> memidx.
Repro:
(module (memory $m0 1) (memory $m1 1)
(func (export "go")
i32.const 0
v128.load (memory 1)
drop))
Before: printed memidx 0 with offset 1.
After: prints memidx 1 with offset 0.
