2c58709023 glsl/int64: Fix a typo in imod64
The zy swizzle gives us one component of quotient and one component of
remainder.  What we wanted was zw for the remainder.

695b04f7eb glsl: Add "built-in" functions to do 64%64 => 64 modulus
These functions are directly available in shaders.  A #define is added
to detect the presence.  This allows these functions to be tested using
piglit regardless of whether the driver uses them for lowering.  The
GLSL spec says that functions and macros beginning with __ are reserved
for use by the implementation... hey, that's us!

v2: Use function inlining.
