Log:
    PR pch/54117
    * c-opts.c (c_common_post_options): If debug info is enabled
    and non-dwarf*, refuse to load PCH files and when writing PCH
    file warn.

    * lib/dg-pch.exp (pch-init, pch-finish,
    check_effective_target_pch_supported_debug): New procs.
    (dg-flags-pch): If $pch_unsupported, make tests UNSUPPORTED.
    Likewise if $pch_unsupported_debug and $flags include -g.
    Skip FAILs about missing *.gch file if $pch_unsupported_debug
    and dg-require-effective-target pch_unsupported_debug.
    * g++.dg/pch/pch.exp: Call pch-init and pch-finish.
    * objc.dg/pch/pch.exp: Likewise.
    * gcc.dg/pch/pch.exp: Likewise.
    * gcc.dg/pch/valid-1.c: Add dg-require-effective-target
    pch_unsupported_debug.
    * gcc.dg/pch/valid-1.hs: Likewise.
    * gcc.dg/pch/valid-1b.c: Likewise.
    * gcc.dg/pch/valid-1b.hs: Likewise.
