Nikita Popov 4c088c5da7 Handle warnings during sccp function evaluation ...

Some upcoming changes like https://wiki.php.net/rfc/deprecate_null_to_scalar_internal_arg
will make it somewhat inconvenient to determine whether a given
function invocation will generate a diagnostic. Rather than trying
to exclude this in advance, call the function with diagnostics
suppressed, and check whether anything was thrown.

This adds a new EG flag that is kept specific to the SCCP use-case.
This does not use the error_cb hook as it is a (non-TLS) global,
and doesn't fully suppress error handling besides.

Test this by removing the in advance checks for implode and array_flip.
