RISC-V: Promote Zaamo/Zalrsc to a when using an old binutils
Binutils 2.42 and before don't support Zaamo/Zalrsc. When users specify both Zaamo and Zalrsc, promote them to 'a' in the -march string. This does not affect testsuite results for users with old versions of binutils. Testcases that failed due to 'call'/isa string continue to fail after this PATCH when using an old version of binutils. gcc/ChangeLog: * common/config/riscv/riscv-common.cc: Add 'a' extension to riscv_combine_info.
