parse.y: remove coverage-related code fragments

The code fragments that initializes coverage data were scattered into
both parse.y and compile.c.  parse.y allocated a coverage data, and
compile.c initialize the data.

To remove this cross-cutting concern, this change moves the allocation
from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c.
For the sake, parse.y just counts the line number of the original source
code, and the number is passed via rb_ast_body_t.
