RelExpr enumerators are named `R_*`, which can be confused with ELF
relocation type names. Rename the target-specific ones to `RE_*` to
avoid confusion.
For consistency, the target-independent ones can be renamed as well, but
that's not urgent. The relocation processing mechanism with RelExpr has
non-trivial overhead compared with mold's approach, and we might make
more code into Arch/*.cpp files and decrease the enumerators.

so that we can remove the global `ctx` from toString implementations.
Rename lld::toString (to lld:🧝:toStr) to simplify name lookup (we
have many llvm::toString and another lld::toString(const llvm::opt::Arg
&)).
Since Ctx &ctx is a member variable,

e2f0ec3a3a8a2981be8a1aac2004cfb9064c61e8 can be reverted.
also rename `TargetInfo *getXXXTargetInfo` to `void setXXXTargetInfo`
and change it to set `ctx.target`. This ensures that when `ctx` becomes
a local variable, two lld invocations will not reuse the function-local
static variable.

([ELF] Initialize TargetInfo members).

and change it to set `ctx.target`. This ensures that when `ctx` becomes
a local variable, two lld invocations will not reuse the function-local
static variable.
Remove the global variable `symtab` and add a member variable
(`std::unique_ptr<SymbolTable>`) to `Ctx` instead.
This is one step toward eliminating global states.

Ctx was introduced in March 2022 as a more suitable place for such
singletons.
llvm/Support/thread.h includes <thread>, which transitively includes
sstream in libc++ and uses ios_base::in, so we cannot use `#define in ctx.sec`.
`symtab, config, ctx` are now the only variables using
LLVM_LIBRARY_VISIBILITY.
