Subject: [PATCH] glsl/ir_builder: Add more helpers for constructing
 expressions

Add the following functions, each of which construct the similarly named
ir expression:
    div, round_even, clamp

    equal, less, greater, lequal, gequal

    logic_not, logic_and, logic_or

    bit_not, bit_or, bit_and, lshift, rshift

    f2i, i2f, f2u, u2f, i2u, u2i
