When starting with a string that looks like '0xFF', numifying it should
truncate it to 0 - consistent with 0b and 0 which only have an effect on
bare number parsing. This behavior seems to have changed in 5.30.

5.28:
> perl -Mwarnings -e 'print "0xFF" + 0, "\n"'
Argument "0xFF" isn't numeric in addition (+) at -e line 1.
0

5.30:
> perl -Mwarnings -e 'print "0xFF" + 0, "\n"'
Argument "0xFF" isn't numeric in addition (+) at -e line 1.
255

It also seems to have had this behavior way back in 5.6:
> perl -Mwarnings -e 'print "0xFF" + 0, "\n"'
Argument "0xFF" isn't numeric in addition (+) at -e line 1.
255
