Skip a number of C++ test cases for '-fno-exceptions' testing

Running 'make check' with: 'RUNTESTFLAGS=--target_board=unix/-fno-exceptions',
'error: exception handling disabled' is triggered for C++ 'throw' etc. usage,
and per 'gcc/testsuite/lib/gcc-dg.exp:gcc-dg-prune':

    # If exceptions are disabled, mark tests expecting exceptions to be enabled
    # as unsupported.
    if { ![check_effective_target_exceptions_enabled] } {
	if [regexp "(^|\n)\[^\n\]*: error: exception handling disabled" $text] {
	    return "::unsupported::exception handling disabled"
	}

..., which generally means:

    -PASS: [...] (test for excess errors)
    +UNSUPPORTED: [...]: exception handling disabled

However, if there are additional 'dg-error' etc. directives, these may regress
PASS -> FAIL (or similar) -- if their associated diagnostics are precluded by
'error: exception handling disabled'.  For example:

    PASS: g++.dg/cpp2a/explicit1.C    (test for errors, line 43)
    PASS: g++.dg/cpp2a/explicit1.C    (test for errors, line 47)
    [-PASS:-]{+FAIL:+} g++.dg/cpp2a/explicit1.C    (test for errors, line 50)
    [-PASS:-]{+FAIL:+} g++.dg/cpp2a/explicit1.C    (test for errors, line 51)
    PASS: g++.dg/cpp2a/explicit1.C    (test for errors, line 52)
    PASS: g++.dg/cpp2a/explicit1.C    (test for errors, line 53)
    PASS: g++.dg/cpp2a/explicit1.C    (test for errors, line 59)
    [-PASS:-]{+UNSUPPORTED:+} g++.dg/cpp2a/explicit1.C  [-(test for excess errors)-]{+: exception handling disabled+}

Specify 'dg-require-effective-target exceptions_enabled' for those test cases.
