Previously, `asm.mov(m32, imm32)` panicked when `imm32 > 0x80000000`. It
attempted to split imm32 into a register before doing the store, but
then the register size didn't match the destination size.
Instead of splitting, use the `MOV r/m32, imm32` form which works for
all 32-bit values. Adjust asserts that assumed that all forms undergo
sign extension, which is not true for this case.
