This does a bunch of GPR and vector loads to showcase addressing
limitations between ARM and x86.
Tests:
- 8/16/32/64-bit GPR loads
- Both 32-bit and 64-bit addressing modes
- 32/64/128-bit Vector loads
- Both 32-bit and 64-bit addressing modes
- Duplicate the tests for 32-bit addressing mode with a 32-bit process
- Since it should change behaviour.
Untested:
- 8/16-bit vector loadstores since those don't exist on x86
- 16-bit x87 integer load exists but that doesn't go through a vector
load in FEX.
