2016-04-08	simplify a buggy test	Quentin Carbonneaux
	I found it by compiling -O2 and seeing the ABI code fail. Further investigation revealed GCC trimmed away the last iteration of the loop because I was accessing the third element of an array of size two. This is undefined behavior, so GCC "proved" that the last iteration was never run.

2016-04-04	cosmetics in sysv abi	Quentin Carbonneaux
	A struct of size 0 is now marked as passed in memory. All the ABI code assumes structs passed in registers have size at least 8. This could have an impact on the alignment in the stack, but eh, I guess they are rare.

2016-04-01	don't try to keep use counts in abi()	Quentin Carbonneaux
	Abi lowering does not need use counts, but they are needed for instruction selection. I changed main to call filluse() between these two passes.
