Commit 2a26292388fcab0c857c91b2d08074c33abd37e8 made `isExported`
accurate except a few linker-synthesized symbols in finalizeSections.
We can collect these linker-synthesized symbols into a vector
and avoid recomputation for other symbols.
This is reland of 1a4d6de1b532149b10522eae5dabce39e5f7c687 after
`isExported` has been made accurate by f10441ad003236ef3b9e5415a571d2be0c0ce5ce
`includeInDynsym` has a special case for isUndefWeak and
--no-dynamic-linker, which can be removed if we simplify disallow
dynamic symbols for static-pie.
The partition feature reports errors only when a symbol `isExported`.
We need to link in a DSO to trigger the mips error.

Related to #95949. A developer with no prior lld contribution and very
little AMD contribution sneaked in these application-specific section
order rules we discourage.

Port https://reviews.llvm.org/D117354 from the MachO port.
If both --symbol-ordering-file and call graph profile are present, the
--symbol-ordering-file takes precedence, but the call graph profile is
still used for symbols that don't appear in the order file.
In addition, call graph profile described sections are now ordered
before other sections.
isExported, intended to replace exportDynamic, is primarily set in two
locations, (a) after parseSymbolVersion and (b) during demoteSymbols.
In the future, we should try removing exportDynamic. Currently,
merging exportDynamic/isExported would cause
riscv-gp.s to fail:
* The first isExported computation considers the undefined symbol exported
* Defined as a linker-synthesized symbol
* isExported remains true, while it should be false
In #86751 we moved the IRELATIVE relocations to .rela.plt when
--pack-dyn-relocs=android was enabled but we neglected to also move
the __rela_iplt_{start,end} symbols. As a result, static binaries
linked with this flag were unable to find their IRELATIVE relocations.
Fix it by having the symbols surround the correct section.
