MOVZ & MOVK

[Kyle-Mitchell]

717 registerFile[destReg] = immediate << quadrantShift;
726 registerFile[destReg] = registerFile[destReg] | (immediate << quadrantShift);

These two lines of code have immediate as int types. This causes issues with the results of MOVK and MOVZ. Some of the observed issues:

MOVZ X1, 0x8000, LSL #16 will result in X1 having a value of 0xffffffff80000000, this is a sign extended result where sign extension should not happen.

MOVZ X1, 0x8000, LSL #32 will result in X1 having a value of 0x8000.

MOVZ X1, 0x8000, LSL #48 will result in X1 having a value of 0xffffffff80000000, this is wrong in sign and distance.

I can not suggest a fix as I do not have a Java build environment handy.
