These tests should cover the following cases:
- MOV with both zero-extended and sign-extended immediates
- implicit truncation of register contents via ALU32/MOV32
- implicit 32-bit truncation of ALU32 output
- oversized register source operand for ALU32 shift
- right-shift of a number that could be positive or negative
- map access where adding the operation size to the offset causes signed
32-bit overflow
- direct stack access at a ~4GiB offset
Also remove the F_LOAD_WITH_STRICT_ALIGNMENT flag from a bunch of tests
that should fail independent of what flags userspace passes.
