The DLC bit is now set to 1 for all loads when GLC is also set,
but cleared to 0 for all stores (otherwise it causes issues),
and also cleared to 0 for atomics.

And use a new p_discard_early_exit instruction. This fixes some cases
where a definition having the same register as an operand causes issues.
v2: rename instruction to p_exit_early_if
v2: modify the existing instruction instead of creating a new one
v3: merge the "i == num - 1" IFs

I thought I fixed this, but I guess I must have broken it again.

This simplifies ACO and allows the lowered code to be optimized (in
particular, constant folded).
Totals from affected shaders:
SGPRS: 1776 -> 1776 (0.00 %)
VGPRS: 1436 -> 1436 (0.00 %)
Spilled SGPRs: 0 -> 0 (0.00 %)
Spilled VGPRs: 0 -> 0 (0.00 %)
Private memory VGPRs: 0 -> 0 (0.00 %)
Scratch size: 0 -> 0 (0.00 %) dwords per thread
Code Size: 203452 -> 203564 (0.06 %) bytes
LDS: 0 -> 0 (0.00 %) blocks
Max Waves: 103 -> 103 (0.00 %)
At least some of the code size increase seems to be from literals being
applied to instructions as a result of constant folding.
v2: remove fmod/frem handling in init_context()
