Commit Message
The .option arch/rvc/norvc/push/pop directives can only take effect for a
small/large specific code region, so they are not file-level architecture
setting. They should only affect the mapping symbols only rather than the
file-level elf architecture attribute. Otherwise, the elf architecture
attribute will appear to missing some extensions when -flto merges files
with different .option architecture settings.

PR 32014
* config/tc-riscv.c (file_arch_str): New const char *, rather than the
arch_str in the riscv_rps_as.subset_list, it's file-level so only be
affected by .attribute arch directive.
(riscv_reset_subsets_list_arch_str): Renamed to riscv_set_arch_str, and
also can handle both file_arch_str and arch_str in subset_list, just
give the pointer address as the input.
(riscv_set_arch): Called by -march and .attribute arch, so set both
file_arch_str and arch_str in subset_list.
(s_riscv_option): Updated .option arch/rvc/norvc/push/pop that only
set the arch_str in subset_list.
(riscv_write_out_attrs): Output elf architecture attribute according to
file_arch_str. Freed file_arch_str.
* doc/c-riscv.texi: Added destrbution that .option directives shouldn't
affect the elf attribute settings.
* testsuite/gas/riscv/option-arch.s: From option-arch-01/02/03 merged.
* testsuite/gas/riscv/option-arch-dis.d: Likewise, for dis-assembler.
* testsuite/gas/riscv/option-arch-attr.d: Likewise, to check readelf -A.

It's not expected that options are changed in this manner during regular use,
but there are a handful of esoteric cases like the one above where users need
to disable particular features of the assembler for particular code sequences.

+However, it's also useful to enable/disable the extensions for some specific
+code regions by @samp{.option arch, +-}. This is very common in the ifunc
