glsl: Make most ir_instruction::as_subclass() functions non-virtual.

There are several common ways to check whether an object is a particular
subclass: dynamic_cast<>, the as_subclass() pattern, or explicit enum
tags.  We originally used the virtual as_subclass methods, but later
added enum tags as they are much nicer for debugging.

Since we have the enum tags, we don't necessarily need to use virtual
functions to implement the as_subclass() methods.  We can just check the
tag and return the pointer or NULL.

This saves 18 entries in the vtable, and instead of two pointer
dereferences per as_subclass() call most are only three inline
instructions.

Compile time of sam3/112.frag (the longest compile in a recent shader-db
run) is reduced by 5% from 348 to 329 ms (n=500).

perf stat of this workload shows:

i965: Skip IR annotations with INTEL_DEBUG=noann.

Running shader-db with INTEL_DEBUG=noann reduces the runtime
from ~90 to ~80 seconds on my machine. It also reduces the disk space
consumed by the .out files from 660 MB (676 on disk) to 343 MB (358 on

i965/fs: Debug the optimization passes by dumping instr to file.

With INTEL_DEBUG=optimizer, write the output of dump_instructions() to a
file each time an optimization pass makes progress. This lets you easily
diff successive files to see what an optimization pass did.

Example filenames written when running glxgears:
   fs8-0000-00-start
   fs8-0000-01-04-opt_copy_propagate
   fs8-0000-01-06-dead_code_eliminate
   fs8-0000-01-12-compute_to_mrf
   fs8-0000-02-06-dead_code_eliminate
        |   |  |   |
        |   |  |   `-- optimization pass name
        |   |  |
        |   |  `-- optimization pass number in the loop
        |   |
        |   `-- optimization loop interation
        |
        `-- shader program number

Note that with INTEL_DEBUG=optimizer, we disable compact_virtual_grfs,
so that we can diff instruction lists across loop interations without
the register numbers being changes.
