Always pass explicit location to fatal_error.

The patch <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00698.html>
adding an overload for fatal_error that passes an explicit location
broke gcc.pot regeneration because xgettext cannot handle function
overloads with the diagnostic string argument in different positions.

As the desired direction is for all diagnostics to have explicit
locations, this patch addresses the regression by removing the version
of fatal_error that does not pass a location, passing explicit
input_location everywhere (in the hope that those will incrementally
be changed to other locations, much as with the addition of a location
argument to pedwarn some time ago - a lot of cases aren't meaningfully
associated with a source file so UNKNOWN_LOCATION may be better).

Note that this patch does not attempt to fix any existing issues with
these diagnostics (such as wrongly starting with capital letters or
ending with '.' or '\n'); it just adds the input_location argument.

Bootstrapped with no regressions for x86_64-unknown-linux-gnu (Go
excluded).

compiler: Fix -fgo-prefix handling.

There was bug in the fix for PR 61880: it only worked fully
correctly for code compiled with -fgo-pkgpath.  For code that
used -fgo-prefix, or that used neither option, the '.'
separating the prefix and the package name was converted to an
underscore, which did not happen before.  This broke SWIG and
any other code that expected specific symbol names.
Fortunately all code compiled in libgo and all code compiled
by the go tool uses -fgo-pkgpath, so this probably did not
affect very many people.

This is an incomplete fix that does not modify the package
file format, for use on both mainline and the GCC 4.9 branch.
A follow on patch will fully fix the problem.
