    c++: -Wdeprecated-copy and #pragma diagnostic [PR94492]

    -Wdeprecated-copy was depending only on the state of the warning at the
    point where we call the function, making it hard to use #pragma diagnos=
tic
    to suppress the warning for a particular implicitly declared function.

    But checking whether the warning is enabled at the location of the impl=
icit
    declaration turned out to be a bit complicated; option_enabled only tes=
ts
    whether it was enabled at the start of compilation, the actual test only
    existed in the middle of diagnostic_report_diagnostic.  So this patch
    factors it out and adds a new warning_enabled function to diagnostic.h.
