Lioncash 41fee1c940 armemu: Unset GE flags for UADD8 if results are < 0x100

Lioncash 58dc554733 armemu: Fix SSUB16 
Broken from the same reason SADD16 was.

The lo part of the result should only be constructed from the lo halfwords of rm and rn.
The hi part of the result should only be constructed from the hi halfwords of rm and rn.

Lioncash 2d91164bb9 armemu: Narrow the scope of some variables in handle_v6_insn

Lioncash 5289a496a7 armemu: Fix SADD16 
The lo and hi parts of the result were being constructed as a result of hi and lo halfword intermixing from the rm and rn regs. However the lo part of the result should be constructed only from the lo halfwords of rm and rn, and the hi part of the result should only be constructed from the hi halfwords of rm and rn.
