Track where l-values are required in AST traversal This functionality is refactored out of EmulatePrecision to be a common feature of TIntermTraverser. This is done since tracking where l-values are required will be useful for other traversers. For example, it will be needed for converting dynamic indexing of matrices and vectors to function calls. This change adds some overhead to all tree traversers, but the overhead is expected to be small for typical shaders which don't contain too many user-defined functions.
