    ipa: Fix throw in multi-versioned functions [PR106627]

    Any multi-versioned function was implicitly declared as noexcept, which
    leads to an abort if an exception is thrown inside the function.
    The reason for this is that the function declaration is replaced by a
    newly created dispatcher declaration, which has TREE_NOTHROW always set
    to 1. Instead we need to set TREE_NOTHROW to the value of the original
    declaration.

    gcc/ChangeLog:

            * config/i386/i386-features.cc
(ix86_get_function_versions_dispatcher):
            Set TREE_NOTHROW correctly for dispatcher declaration.
            * config/rs6000/rs6000.cc
(rs6000_get_function_versions_dispatcher):
            Likewise.

    gcc/testsuite/ChangeLog:

            * g++.target/i386/pr106627.C: New test.=
