Options

Robust distinction between IDENTIFIER and TYPE_NAME tokens.

To distinguish the tokens we used to track the lexer context, which is fragile. This patch implements a better way - combine the two tokens into a common parser rule and let the parser context decide if the declaration is valid, which it already does by checking the naming conflicts. TEST=WebGL conformance tests.
