We're about to add new implicit conversions, first for ARB_gpu_shader5,
and then later for ARB_gpu_shader_fp64. Pull out the opcode
determination into its own function, and get rid of the bool -> float
case that could never be hit anyway [since it fails the is_numeric()
check].
V2: Retain the vector width mangling. It turns out this is necessary for
the conversions done (and then thrown away) when determining the return
type of arithmetic operators.

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:
24.14% reduction in iTLB-loads: 285,543 -> 216,606
42.55% reduction in iTLB-load-misses: 18,785 -> 10,792

Now that the constructors set a type, ir_type_unset is not very useful.
Move it to the end of the enum (specifically out of position 0) so that
enums checks for dereferences and rvalues can save an instruction.

Makes checking whether an object is an ir_dereference, an ir_rvalue, or
an ir_jump simpler. Since ir_dereference is a subclass or ir_rvalue,
list its subtypes first so that they can both generate nice code.

This has the added perk that if you forget to set ir_type in the
constructor of a new subclass (or a new constructor of an existing

ir_validate or similar run-time detection.

Same as b026b6bbfe, but
COLOR_ARRAY_SIZE/SECONDARY_COLOR_ARRAY_SIZE.
Ideally we wouldn't munge the incoming state, so that we wouldn't need
to unmunge it back on glGet*. But the array size state is copied and
referred in many places, many of which couldn't take an GLenum like
GL_BGRA instead of a plain integer. So just hack around on glGet*,
to ensure there is no risk of introducing regressions elsewhere.

brw_set_conditionalmod and brw_next_insn work together to set the
conditional modifier for the next instruction, then turn it off.
The Gen8+ generators don't implement this: we just set it for all future
instructions, and whack it for each fs_inst/vec4_instruction.
Both approaches work out because we only set conditional_mod on
IR instructions like CMP, AND, and so on, which correspond to exactly
one assembly instruction. The Gen8 generators would break if we had
an IR instruction that generated multiple instructions, and the Gen4-7
EU emit layer would do...something.
To safeguard against this, assert that we only generated one instruction
if conditional_mod is set, and just set the flag directly on that
instruction rather than altering default state.

brw_set_conditionalmod has traditionally been complex: it causes
conditionalmod to be set for the next instruction, and then predication
to be set on all future instructions after that.
We may want to generate a flag condition and not use it immediately,
due to instruction scheduling or the like. Even if not, it's easy
to set things explicitly, and that's clearer.

brw_CMP already takes a conditional modifier as a parameter, and sets it

predicated.

Often times, we want to emit an instruction, then set one field on it,

declare "struct brw_instruction *inst;" and then use "inst =
brw_FOO(...)" to emit the instruction, which can hurt readability.
The new "brw_last_inst" macro refers to the most recently emitted
instruction, so you can just do:
brw_ADD(...)
brw_last_inst->header.predicate_control = BRW_PREDICATE_NORMAL;
