jit/decoder: Add generated arm32 tests

Browse source 
Introduces the first unit tests for the ARM32 JIT decoder. A new script
automatically generates a test case for every instruction in arm32.inc,
providing 100% of the isa.

This also includes a critical rework of the decoder's lookup table
generation logic. The previous hashing method was flawed, causing
build-time overflows and incorrect instruction matching (shadowing) for
patterns with wildcards. The new algorithm correctly populates the
lookup table.
