Context: there are currently two types of line number supported in
dg-{error,warning,message,bogus} directives: absolute and relative.  With an
absolute line number, it's immediately clear what line number is meant, but
when a line is added at the start of the file, the line number needs to be
updated.  With a relative line number, that problem is solved, but when relative
line numbers become large, it becomes less clear what line it refers to, and
when adding a line inbetween the directive using the relative line number and
the line it refers to, the relative line number still needs to be updated.

Add a directive dg-line with argument varname, that saves the line number
of the directive in a variable varname, which can be used as line number in dg
directives.

PR target/80482

This patch changes the parameter testing for powerpc vector builtins to relax
the existing requirement that the parameters be identical to instead that they
be compatible.  This allows for mixing parameters with differing qualified
(const, volatile, etc.) types.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80482 for more information.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64be-unknown-linux-gnu with no regressions.  Is this ok for trunk?
