Implemented the option to omit Power10 instructions from save stubs via the
option --no-power10-stubs or --power10-stubs=no on lld. --power10-stubs= will
override the other option. --power10-stubs=auto also exists to use the default
behaviour (ie allow Power10 instructions in stubs).

GNU as does not sort local symbols. This has several advantages:
* The .symtab order is roughly the symbol occurrence order.
* The closest preceding STT_SECTION symbol is the definition of a local symbol.
* The closest preceding STT_FILE symbol is the defining file of a local symbol, if there are multiple default-version .file directives. (Not implemented in MC.)
Thunk alignment is added in thie patch when using pc-rel instructions
to avoid crossing the 64 byte boundary.

R_PPC64_REL24_NOTOC. This indicates that the caller does not have a valid TOC
pointer in R2 and does not require R2 to be restored after the call.
This patch is added to support local calls to callees that require a TOC
