[ELF] Update st_size when merging a common symbol with a shared symbol
When a common symbol is merged with a shared symbol, increase st_size if
the shared symbol has a larger st_size. At runtime, the executable's
symbol overrides the shared symbol. The shared symbol may be created
from common symbols in a previous link. This rule makes sure we pick
the largest size among all common symbols.
This behavior matches GNU ld. See
https://sourceware.org/bugzilla/show_bug.cgi?id=25236 for discussions.
A shared symbol does not hold alignment constraints. Ignore the
alignment update.
