[PATCH] Don't munge yacc's #line directives

[Patrick Palka]

The #line directives within GDB's autogenerated yacc files (e.g.
c-exp.c) are being munged by a dubious sed expression that is causing
these directives to refer to nonexistent source files.  As a result it
is currently not possible to debug these source files at source level.

The culprit sed expression was added by commit 954d8cae for non-obvious
reasons.  My guess is that the expression was added to work around a bug
in ylwrap which has since been fixed upstream: if I revert the November
2014 update to ylwrap, commit be3046511, then the culprit sed line no
longer causes the above mentioned issue.

So this patch removes the culprit sed script since it does not seem
needed anymore; the emitted #line directives look and work fine without
it.
