[PATCH, rs6000] Split up rs6000.c.

The source file rs6000.c has grown to unreasonable size and is being
split up into several smaller source files.  This should improve
compilation speed for building gcc.

This is the first of several patches to do this and moves most of the
prologue/epilogue code to a new source file.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions.  Is this ok for trunk?

[Darwin, testsuite] Fix isystem-2.c.

For the test to succeed there needs to be some header that is to be found in
the 'expected' place i.e. <sysroot>/usr/include/.  It's important that it is
not the name of a header for which fixincludes have been applied, since such
headers will be found in the gcc include-fixed dir and, in general, reference
additional headers.  The dummy sysroot will prevent the additional headers
from being found, resulting in a failed test.  The fix is to use a header name

compiler: edit error messages to avoid -Wformat-diag warnings

    GCC recently introduced -Wformat-diag to scrutinize GCC error messages.
    It reports a number of warnings about gofrontend code, such as:

    ../../trunk/gcc/go/gofrontend/import.cc: In member function ‘Type* Import::type_for_index(int, const string&, size_t, bool*)’:

    GCC recently added a new warning -Wformat-diag which does a lot of
    rigorous checks on GCC diagnostic messages.  This produces a number of
    unnecessary diagnostics on gofrontend diagnostic output, such as

    ../../trunk/gcc/go/gofrontend/escape.cc: In member function ‘virtual int Escape_analysis_assign::statement(Block*, size_t*, Statement*)’:
    ../../trunk/gcc/go/gofrontend/escape.cc:1336:33: warning: spurious leading punctuation sequence ‘[’ in format [-Wformat-diag]

     1964 |         "esccall:: indirect call <- %s, untracked",
          |                                  ^

    Avoid these messages by adding a new function go_debug that uses only
    printf formatting, not GCC diagnostic formatting, and change all the
    optimization debugging messages to use it.  None of the debugging
    messages used the GCC diagnostic formatting specifiers anyhow.

Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers.  However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10.  This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__.  The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.

compiler: omit write barrier for assignment to *(convert(&local))

    Assignments to local variables don't need a write barrier. But
