Fix parsing integers larger than 0x7FFFFFFF Parsing should accept all values between 0 and 0xFFFFFFFF as specified in ESSL 3.00 section 4.1.3. When a signed literal is parsed, it's interpreted as if it specifies the bit pattern of a two's complement integer. For example, parsing "0xFFFFFFFF" results in -1. Decimal literals behave the same way, so for example parsing "3000000000" results in -1294967296. This change affects parsing of literals in ESSL 1.00 as well. In ESSL 3.00, an out-of-range integer literal now generates a compiler error. Unit tests are added based on examples in the ESSL 3.00 spec and one example in GLSL 4.5 spec that ESSL should match.
