How would you propose handling the fact that the full table would have
combined cpp / C / linker / assembler options (plus C++ / fortran
etc. specific ones)?  It would probably also need some target-specific
options; I've not got much experience in that area.

Maybe we have one master .tab file, for consistency across everything,
and process it through different scripts at GCC compile time depending
upon the user?  gcc.c would want a script that combines everything and
sorts it; other scripts could filter it for whatever toplev.c or
c-decl.c or cp/decl2.c etc. require?
