Cherry Mui 8dc7710fae cmd/compile: do not use content addressable symbol for generic iface method names
When a generic interface method is used, we use a special
relocation R_USEGENERICIFACEMETHOD to tell the linker the name of
the generic interface method, so it can keep methods with that
name live. The relocation references a symbol whose content is the
name. Currently this is a string symbol, which is content
addessable and may have trailing zero bytes (for better
deduplication). The trailing bytes can cause confusion for the
linker. This symbol doesn't need to be in the final binary and
doesn't need to be deduplicated with other symbol. So we don't use
content addressable symbol but make an (unnamed) symbol
specifically for this.

May fix #54346.
