2021-07-23glasm: Fix INeg32 on negative immediatesReinUsesLisp1-1/+5
2021-07-23glasm: Catch more register leaksReinUsesLisp1-18/+40
Add support for null registers. These are used when an instruction has no usages. This comes handy when an instruction is only used for its CC value, with the caveat of having to invalidate all pseudo-instructions before defining the instruction itself in the register allocator. This commits changes this. Workaround a bug on Nvidia's condition codes conditional execution using branches.
