From comment in emit_mimg():
We don't need the bias, sample index, compare value or offset to be
computed in WQM but if the p_create_vector copies the coordinates, then it
needs to be in WQM.

This makes for a more self-describing iteration behavior, and it gets rid
of the need for the duplicated "final check" at the bottom.

All code paths that set "found" to true either break or return before the
loop header is reached again, so the checks are unnecessary.

This mainly clarifies the semantics of register bounds (inclusive vs
exclusive), and further groups related varaibles together to clarify
sliding-window-style loops.

Delaying the call to adjust_max_used_regs until after get_regs_for_copies
returns puts the RA context into a state where registers past max_used_gpr
may be blocked. This isn't an issue on its own, but it adds a surprising
corner case to get_reg_simple that is easily avoided now.

When both operands of a v_sub (same apply for v_add) are mul and one
already uses clamp/omod, pick the other operand to get a chance to
combine to a MAD.

When there are no param exports in an NGG (or legacy VS) shader,
the NO_PC_EXPORT=1 is set, which means PS waves can launch before
the current stage finishes.
If the current stage has any stores, we need to make sure to wait for
those before we allow PS waves to start, so that PS can read what
these instructions stored.
