d6594ae54c Added support for machine specific constantpool values. These are useful for
representing expressions that can only be resolved at link time, etc.

52a51e38dc Emit .set directives for jump table entries when possible, which reduces
the number of relocations in object files, shrinkifying them.

4a6bd33da0 Instead of blindly looking past constantexpr casts, actually constant
fold them.  This correctly truncates constants that are too large for the
destination slot and makes the code easier to understand.  This fixes PR853

37efe67645 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
