Move innermost_block_tracker to expression.h

I think parser-defs.h should hold declarations that can be used by
parser implementations, whereas expression.h should hold declarations
that are used by code that wants to call a parser.  Following this
logic, this patch moves innermost_block_tracker to expression.h.
