50cdccf3ef Added a gcc preprocessor options -P, -P1 
tcc -E -P
  do not output a #line directive, a gcc compatible option

tcc -E -P1
  don't follow a gcc preprocessor style and do output a standard
  #line directive. In such case we don't lose a location info when
  we going to compile a resulting file wtith a compiler not
  understanding a gnu style line info.

40418f87c7 Move a line_ref variable from tcc_preprocess() function into struct BufferedFile. 
This id needed for a right ouput in other places,
precisely to calculate a number of empty lines which are waiting to output.

5e3e321474 A preprocessor should Interpret an input line "# NUM FILENAME" as "#line NUM FILENAME" 
A cpp from gcc do this.
A test case:
     tcc -E tccasm.c -o tccasm.i
     tcc -E tccasm.i -o tccasm.ii
After a patch the line numbers in tccasm.ii are the same
as in tccasm.i

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.

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)
