update parser to handle leading error tokens

This is the first of several CLs that move error tokens to the head
of the token stream so that parser handling of error tokens
can be simplified and less error prone.

In this particular CL:
- update parser to handle error tokens at the head of the token stream
- remove several places that analyzer was preprocessing error tokens
   now that the parser handles them
