glsl: Add IR builder shortcuts for a bunch of random opcodes.
Adding new convenience emitters makes it easier to generate IR involving
these opcodes.
bitfield_insert is particularly useful, since there is no expr() for
quadops.
v2: Add fma() and rename lrp() operands to x/y/a to match the GLSL
specification (suggested by Matt Turner). Fix whitespace issues.
