Ethan Nicholas bf4a7d5235 Fixed DSLParser crash with invalid swizzle
In response to a non-identifier token after a dot, DSLParser would
attempt to swizzle a zero-length field and fail an assertion.

The same basic code path exists in the old compiler, but the resulting
parse error causes the process to abort before it attempts to process
the zero-length swizzle.
