[MC] Parse SHF_LINK_ORDER argument before section group name (#77407)
When both SHF_LINK_ORDER | SHF_GROUP flags are set, GNU assembler from
2.35 onwards (https://sourceware.org/PR25381
https://sourceware.org/binutils/docs/as/Section.html) parses the
SHF_LINK_ORDER argument before section group name, different from us.
This is unfortunate, but does not matter because the `.section` flag `o`
is a niche feature only used by compiler instrumentations, not adopted
by hand-written assembly, and using both flags is extremely rare. Let's
just match GNU assembler. There is another benefit: we now support
zero-flag section group with the SHF_LINK_ORDER flag, while previously
there isn't a syntax.
While here, print 'G' after 'o' to be clear that the 'G' argument is
parsed after the 'o' argument. To make the diff smaller, we don't print
'G' after 'w' in the absence of 'o' for now.

Revert "[RISCV] Remove -riscv-no-aliases in favour of new -M no-aliases"
The replacement doesn't work for llc, but it is needed by
patchable-function-entry.ll.
This reverts commit aa9a30b83a06e3e5e
