These can be simplified with the knowledge of how arguments are
assigned to obj.Prog objects on PPC64. If the argument is not
a register type, the Reg argument (a2 in optab) of obj.Prog is
not used, and those arguments are placed into RestArgs (a3, a4, a5
in optab).
This relaxes the special case handling enforced by IsPPC64RLD and
IsPPC64ISEL. Instead, arguments are assigned as noted above, and
incorrect usage of such opcodes is checked by optab rules, not by
the assembler front-end.
Likewise, add support for handling 6 argument opcodes, these do
not exist today, but will be added with ISA 3.1 (Power10).
Finally, to maintain backwards compatibility, some 4-arg opcodes
whose middle arguments are a register and immediate, could swap
these arguments and generate identical machine code. This likely
wasn't intended, but is possible. These are explicitly fixed up
in the backend, and the asm tests are extended to check these.

When naming case variables, the unified frontend was using
typecheck.Lookup, which uses the current package, rather than
localIdent, which uses the package the variable was originally
declared in. When inlining across package boundaries, this could cause
the case variables to be associated with the wrong package.
In practice, I don't believe this has any negative consequences, but
it's inconsistent and triggered an ICE in typecheck.ClosureType, which
expected all captured variables to be declared in the same package.
Easy fix is to ensure case variables are declared in the correct
package by using localIdent.
Fixes#54912.
