40f7e11c53 tccgen.c: Make sure that gen_op always returns an rvalue. 
Either this fix, or an alternative one, is required for arm64.

6d055312a2 aarch64: Fix -run. 
This adds some more support for properly transfering some
offsets over the different stages of a relocations life.
Still not at all psABI compliant and DSOs can't yet be generated.
But it runs the testsuite in qemu-arm64.

tccelf.c: Add put_elf_reloca, a generalisation of put_elf_reloc.
tccgen.c: On x86_64, use greloca instead of greloc in init_putv.

ff3f9aa6ba Fix handling of case_reg in switch statement. 
The back end functions gen_op(comparison) and gtst() might allocate
registers so case_reg should be left on the value stack while they
are called and set again afterwards.

178275dc0c Don't build libtcc1 with -fstack-protector-strong 
Prevent libtcc1.a to be compiled with -fstack-protector-strong, so that
linking with tcc doesn't fail because symbol '__stack_chk_fail_local' is
not present in libtcc1.a. This is useful only if the CFLAGS passed from
the main Makefile contain this flag.

14745bdeb7 tccgen: nocode_wanted: do not output constants 
This for example suppresses string constants such as with

    int main()
    {
        return sizeof "foo";
    }

Actually, setting

    nocode_wanted = 1;

in libtcc.c for the initial global level seemed wrong, since
obviously "nocode_wanted" means code as any side effects, also
such as string constants.

This reverts a part of 2de1b2d14c
(documented as "Some in-between fixes" in Changelog)

6e0a658e96 win64: try to fix linkage 
- revert to R_X86_64_PC32 for near calls on PE
- revert to s1->section_align set to zero by default

Untested. Compared to release_0_9_26 the pe-image looks back to
normal.  There are some differences in dissassembly (r10/r11 usage)
but maybe that's ok.
