    testsuite: gdc: Require ucn in gdc.test/runnable/mangle.d etc. [PR104739]
    
    gdc.test/runnable/mangle.d and two other tests come out UNRESOLVED on
    Solaris with the native assembler:
    
    UNRESOLVED: gdc.test/runnable/mangle.d   compilation failed to produce executable
    UNRESOLVED: gdc.test/runnable/mangle.d -shared-libphobos compilation failed
    to produce executable
    UNRESOLVED: gdc.test/runnable/testmodule.d compilation failed to produce
    executable
    UNRESOLVED: gdc.test/runnable/testmodule.d -shared-libphobos compilation
    failed to produce executable
    UNRESOLVED: gdc.test/runnable/ufcs.d   compilation failed to produce executable
    UNRESOLVED: gdc.test/runnable/ufcs.d -shared-libphobos compilation failed

    since /bin/as lacks UCN support.
    
    Iain recently added UNICODE_NAMES: annotations to the affected tests and
    those recently were imported into trunk.
    
    This patch handles the DejaGnu side of things, adding
    
            { dg-require-effective-target ucn }
    
    to those tests on the fly.
    
    Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11 (as and gas each),
    and x86_64-pc-linux-gnu.
