nv50/ir: improve instruction pipelining on gm107
This makes use of scheduling control codes which are very useful
for improving the instruction pipelining.
This patch will increase performance on Maxwell GPUs by, at least,
x1.5 up to x3.5 for some benchmarks.
Although this has been fairly well tested, I would not be suprised
if someone hit a corner case somewhere. That way, the scheduler
is enabled by default but it can be deactivated by using
NV50_PROG_SCHED=0.
Thanks to Scott Gray for the reverse engineering work available from
https://github.com/NervanaSystems/maxas/wiki/Control-Codes.

gm107/ir: add a legalize SSA pass for PFETCH
PFETCH, actually ISBERD on GM107+ ISA only accepts a GPR for src0.

nvc0/ir: fix up mul+add -> mad algebraic opt, enable for integers
For some reason this has been disabled for integers ever since codegen
was merged, despite there being emission code for IMAD. Seems to work.

nvc0: add maxwell (sm50) compiler backend
The big missing part here is proper sched data calculations, but
hopefully the chosen placeholder will be sufficient for now.
Passes piglit as well as GK107 does.
