Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.

The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.

Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Instead of using a function to resolve symbols that should be supplied by
the dynamic linker itself, use a version script that exposes them. From joerg@
