This introduces testsuite support infra for removing extensions.
Since z* extensions don't have ordering requirements the logic for
adding/removing those extensions has also been consolidated.
This fixes RVWMO compile testcases failing on Ztso targets by removing
the extension from the -march string.
gcc/ChangeLog:
* doc/sourcebuild.texi (dg-remove-option): Add documentation.
(dg-add-option): Add documentation for riscv_{a,zaamo,zalrsc,ztso}
gcc/testsuite/ChangeLog:
* gcc.target/riscv/amo/amo-table-a-6-amo-add-1.c: Add dg-remove-options
for ztso.

Tested using rv64gcv_ztso/rv64id but relying on precommit to run the targets
there.
Beyond testing Ztso/Zalrsc this is also helpful for the Zabha patch I'm
working on. We can continue to test the atomic subword emulation
routines without specifing a -march string.
---
v2 ChangeLog:
Remove spare bracket that pre-commit flagged.
Add missing dg-add-options for zalrsc testcases.
---
v3 ChangeLog:
Add documentation for dg-remove-option and document some existing riscv_*
dg-add-option options.
Approved here: https://inbox.sourceware.org/gcc-patches/9fa5c829-1e30-444c-a091-62d05f2f22ca@gmail.com/
I'll let it sit on the list for an hour or so before committing in case anyone
has feedback on the added docs.
