PR fortran/48720
* gfortran.texi: Document the 'Q' exponent-letter extension.
* invoke.texi: Document -Wreal-q-constant.
* lang.opt: Add -Wreal-q-constant option.
* gfortran.h: Add warn_real_q_constant to option struct.
* primary.c (match_real_constant): Use it. Accept 'Q' as
exponent-letter for REAL(16) real-literal-constant with a
fallback to REAL(10) or error if REAL(10) is not available.
* options.c (gfc_init_options, set_Wall) Set it.
(gfc_handle_option): Handle new option.
