Instructions attached to blocks are never explicitly freed. Let's
use ralloc() to attach those objects to the compiler context so that
they are automatically freed when the ctx object is freed.

This is just a bit of refactoring to simplify MIR.

This allows nodes to be unsigned and prevents a class of weird
signedness bugs identified by Coverity.

We need three independent sources to support indirect SSBO writes (as
well as textures with both LOD/bias and offsets). Now is a good time to
make sources just an array so we don't have to rewrite a ton of code if
we ever needed a fourth source for some reason.

As far as I know, there's no such thing as a load/store op that only
takes its argument in r27. We just need to set the appropriate arg_1
field in the RA to specify other registers if we want them.
To facilitate this, various RA-related changes are needed across the
compiler ; this should also fix indirect offsets which were implicitly
interpreted as "r27-only" despite not even passing through RA yet. One
ripple effect change is switching the move insertion point and adjusting
the liveness analysis accordingly, so while this was intended as a
purely functional change, there are some shader-db changes:

The 16-bit field can be decomposed to two independent 8-bit fields, each
representing a single (additional) argument to the load/store op,
generally used for encoding registers. Addressable registers here are
substantially limited compared to the main register in a load/store op.

Rather than putting registers after SSA in the MIR indexing, put them
side-by-side, shifted 1, using the bottom bit as the SSA/reg select.
This will allow us to generate SSA temps in the compiler.

We add a new opt pass fusing perspective projection with varyings. Minor
win..? We don't combine non-varying projections, since if we're too
agressive, the extra load/store traffic will hurt us so it's not really
a win in practice.

We don't use it yet, since it's actually a shader-db regression. This is
primarily helpful as an intermediate step for attaching projection to
varyings.
