ir3: Rewrite delay calculation
The old delay calculation relied on the SSA information staying around,
and wouldn't work once we start introducing phi nodes and making
"normal" values defined in multiple blocks not array regs anymore.
What's worse is that properly inserting phi nodes when splitting live
ranges would make that code even more complicated, and this was the last
place post-RA that actually needed that information.
The new version only compares the physical registers of sources and
destinations. It works by going backwards up to a maximum number of
cycles, so it might be slightly slower when the definition is closer but
should be faster when it is farther away.
To avoid complicating the new method, the old method is kept around, but
only for pre-RA scheduling and it can therefore be drastically
simplified as the array case can be dropped.
ir3_delay_calc() is split into a few variants to avoid an explosion of
boolean arguments in users, especially now that merged_regs now has to
be passed to it.
The new method is a little more complicated when it comes to handling
(rptN), because both the assigner and consumer may be (rptN). This adds
some unit tests for those cases, in addition to dropping the to-SSA code
in the test harness since it's no longer needed.
Finally, ir3_legalize has to be switched to using physical registers for
the branch condition. This was the one place where IR3_REG_SSA remained
after RA.

ir3: Add ir3_register::array.base
There were two different approaches I saw in the post-RA code for
figuring out what regiser range a relative access touched:
1. Use reg->array.offset and reg->array.size. This is wrong in case
reg->array.offset was non-zero before RA, because array.size is
the size of the whole array and array.offset has the const offset
within the array baked in.
2. Lookup the array from the array ID and use the base + range there.
This is correct, but won't work with the new RA, where an array might
not always be assigned to the same register.
This replaces both methods with a new ir3_register::array.base field,
and switches all the users I could find to it.

ir3: Prepare for instructions with multiple destinations
To simplify the pre-RA merge set code and express the result live-range
splitting in RA, we need to add support for parallel copy instructions,
and for the merge set code these parallel copies need to be in SSA form.
Parallel copies have multiple destinations by necessity, but there was
no way to express this in the existing IR. In particular there was no
support for marking a register as being a destination, and no support
for indicating which destination register out of several an SSA source
refers to. This replaces ir3_register::instr with ir3_register::def and
re-purposes ir3_register::instr. I haven't propagated this into common
helpers, like ssa(), because that would vastly increase the amount of
churn and the number of places that produce such instructions should be
limited -- only RA will create parallel copies and they will be
destroyed right after RA. In the future swz will have multiple
destinations too, but it will only be created after RA via parallel copy
lowering.
