runtime: identify special functions by flag instead of address
When there are plugins, there may not be a unique copy of runtime
functions like goexit, mcall, etc. So identifying them by entry
address is problematic. Instead, keep track of each special function
using a field in the symbol table. That way, multiple copies of
the same runtime function will be treated identically.
Fixes #24351
Fixes #23133
