glsl/ast: Add 64-bit integer support to conversion functions

This adds support to call the new operations on conversions.

v2 (idr): Delete an unnecessary break-statement.  Noticed by Matt.  Add
a missing blank line.  Noticed by Ian.

v3 (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.
