devirtualize Parser

Devirtualize Parser

* src/parser.h: No one inherits from Parser, so the destructor can be
  non-virtual, removing the need for Parser to have a vtable. Also add
  BASE_EMBEDDED to it and to RegExpParser.

LGTM if one comment is addressed.

File src/parser.h (right):

https://codereview.chromium.org/13640007/diff/1/src/parser.h#newcode426
src/parser.h:426: class Parser {
Since we are at it, let's make the parser BASE_EMBEDDED.

Done.  Also added BASE_EMBEDDED for RegExpParser while I was at it.
