Extra validation is added to ir_validate to make sure this is
always updated to the correct numer of operands, as passes like
lower_instructions modify the instructions directly rather then
generating a new one.
The reduction in time is so small that it is not really
measurable. However callgrind was reporting this function as
being called just under 34 million times while compiling the
Deus Ex shaders (just pre-linking was profiled) with 0.20%
spent in this function.
v2:
- make num_operands a unit8_t
- fix unsigned/signed mismatches

This just adds the new operations and add 64-bit integer support to all
the existing cases where it is needed.
v2: fix some issues found in testing.
v2.1: add unreachable (Ian), add missing int/uint pack/unpack (Dave).
v3 (idr): Rebase on top of idr's series to generate
ir_expression_operation_constant.h. In addition, this version:
Adds missing support for ir_unop_bit_not, ir_binop_all_equal,
ir_binop_any_nequal, ir_binop_vector_extract,
ir_triop_vector_insert, and ir_quadop_vector.
Removes support for uint64_t from ir_unop_abs and ir_unop_sign.
v4 (idr): "cut them down later" => Remove ir_unop_b2u64 and
ir_unop_u642b. Handle these with extra i2u or u2i casts just like
uint(bool) and bool(uint) conversion is done.

Immediately previous to this patch,

should be "minimal."
v3: With much help from José Fonseca, fix the SCons build.

(X & -X) calculates a value with only the least significant bit of X
set. Since there is only one bit set, the LSB is the MSB.
v2: Remove extra int() cast. Suggested by Matt.

ir_unop_fract already forbade integer types in ir_validate. ir_unop_rcp,
ir_unop_rsq, and ir_unop_sqrt should also forbid them in ir_validate.

I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.
No difference in OglBatch7 (n=20).
