tccpp.c: In TOK_GET, add comment warning about illegal cast.
...
Also, in tok_str_add2, use memcpy instead of the illegal cast.
Unfortunately, I can't see an easy way of fixing the bug.

tccelf.c: Reset sym after call to build_got.
...
The call to build_got can cause symtab_section->data to be reallocated
(build_got -> add_elf_sym -> put_elf_sym -> section_ptr_add ->
section_realloc -> tcc_realloc). This is not obvious on a cursory
inspection, but fortunately Valgrind spotted it immediately.
Are there other, similar bugs that Valgrind did not detect?

arm64: Implement __clear_cache.

__clear_cache is defined in lib-arm64.c with a single call to
__arm64_clear_cache, which is the real built-in function and is
turned into inline assembler by gen_clear_cache in arm64-gen.c

tccgen.c: Optimise 0<<x, 0>>x, -1>>x, x&0, x*0, x|-1, x%1.
...
More precisely, treat (0 << x) and so on as constant expressions, but
not if const_wanted as we do not want to allow "case (x*0):", ...
Do not optimise (0 / x) and (0 % x) here as x might be zero, though
for an architecture that does not generate an exception for division
by zero the back end might choose to optimise those.

Implementation is mostly shared with __builtin_frame_address.
It seems to work on arm64, i386 and x86_64. It may need to be
adapted for other targets.
