glsl/ast/ir: Add 64-bit integer constant support

This adds support for 64-bit integer constants to the parser,
ast and ir.

v2: fix a few issues found in testing.

v3: Add missing ir_constant copy contructor support.

v4: Use PRIu64 and PRId64 in printfs in glsl_parser_extras.cpp.
Suggested by Nicolai.  Rebase on Marek's linalloc changes.
