AST/SPV: Fix #930: translate uvec4 <-> uint64 for SubgroupGeMask et. al.
On reading built-in variables SubgroupEqMask, SubgroupGeMask, SubgroupGtMask,
SubgroupLeMask, and SubgroupLtMask, the AST expects 64-bit ints, while SPIR-V
is defined as vectors of 32-bit ints.
The declaration type has to be translated in the opposite direction.
