glsl: Add new expressions for INTEL_shader_integer_functions2
v2: Re-write iadd64_saturate and isub64_saturate to avoid undefined
overflow behavior. Also fix copy-and-paste bug in isub64_saturate.
Suggested by Caio.
v3: Avoid signed integer overflow for abs_sub(0, INT_MIN). Noticed by
Caio.
v4: Alternate fix for signed integer overflow for abs_sub(0, INT_MIN).
I tried the previous methon in a small test program with -ftrapv, and it
failed.
