Nico Weber 3eb2fc4b50 [lld/mac] Partially implement -export_dynamic
This implements the part of -export_dynamic that adds external
symbols as dead strip roots even for executables.

It does not yet implement the effect -export_dynamic has for LTO.
I tried just replacing `config->outputType != MH_EXECUTE` with
`(config->outputType != MH_EXECUTE || config->exportDynamic)` in
LTO.cpp, but then local symbols make it into the symbol table too,
which is too much (and also doesn't match ld64). So punt on this
for now until I understand it better.
(D91583 may or may not be related too).
