grischka 30afb50e64 arm64-win32 review: fix problems and pass tests
tccpe.c:
- fix arm64 unwind codes (to make native set/longjmp() work)
  sizeof(RUNTIME_FUNCTION) is 8 on arm64 in the first place
  no need to note stack slots if we don't save any registers anyway

arm64-gen.c:
- fix long double reg-move
- fix arm64_hfa() for structs with float arrays
- gfunc_prolog(): setup stackframe eariler (simplifies unwind codes)
- new function gv_addr(RC);

win32/include/setjmp.h:
- provide correct definition for setjmo() (frameoffset = 224)

tccasm.c:
- support ".quad" with symbol & relocation
- support ".size"
- fix ". - symbol" arithmetic

win32/lib/crt1.c and win32/include/stdlib.h:
- do not write to __argc/__argv which reside in msvcrt.dll
  (msvcrt.dll on arm64 does not like that, crashes on unload)

tcc.c,libtcc.c:
- new functions tcc_fopen/fclose to avoid different stdio unstances
  in tcc.exe & libtcc.dll

tests & github workflow:
- add test-win32.bat to run tests with a tcc compiled by build-tcc.bat
- add msvcrt_start.c for gcc/clang to use the same runtime as tcc

  the problem is that newer gcc as well as clang and cl are
  linking to newer runtimes (such as UCRT) that have partially
  different printf format behavior which makes tcctest fail.

  the solution here is to force these compilers to link with
  msvcrt.dll just like tcc.

  Also, there is no gcc on arm64-win32 currently at all.

  Anyway, this approach to running the github CI tests
  does not require msys2.  But It does rely on gnumake
  as well as on some 'sh' shell though which seems to be
  installed somewhere (maybe it is the one from git).

Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler
-----------------------------------------------------------------------

Features:
--------

- SMALL! You can compile and execute C code everywhere, for example on
  rescue disks.

- FAST! tcc generates machine code for i386, x86_64, arm, aarch64 or
  riscv64.  Compiles and links about 10 times faster than 'gcc -O0'.

- UNLIMITED! Any C dynamic library can be used directly. TCC is
  heading toward full ISOC99 compliance. TCC can of course compile
  itself.

- SAFE! tcc includes an optional memory and bound checker. Bound
  checked code can be mixed freely with standard code.

- Compile and execute C source directly. No linking or assembly
  necessary. Full C preprocessor included.

- C script supported : just add '#!/usr/local/bin/tcc -run' at the first
  line of your C source, and execute it directly from the command
  line.

Documentation:
-------------

1) Installation on Linux, BSD variants or macOS hosts:

   ./configure
   make
   make test
   make install

   Notes: On BSD hosts, gmake should be used instead of make.
   For Windows read tcc-win32.txt.

makeinfo must be installed to compile the doc.  By default, tcc is
installed in /usr/local/bin.  ./configure --help  shows configuration
options.


2) Introduction

We assume here that you know ANSI C. Look at the example ex1.c to know
what the programs look like.

The include file <tcclib.h> can be used if you want a small basic libc
include support (especially useful for floppy disks). Of course, you
can also use standard headers, although they are slower to compile.

You can begin your C script with '#!/usr/local/bin/tcc -run' on the first
line and set its execute bits (chmod a+x your_script). Then, you can
launch the C code as a shell or perl script :-) The command line
arguments are put in 'argc' and 'argv' of the main functions, as in
ANSI C.

3) Examples

ex1.c: simplest example (hello world). Can also be launched directly
as a script: './ex1.c'.

ex2.c: more complicated example: find a number with the four
operations given a list of numbers (benchmark).

ex3.c: compute fibonacci numbers (benchmark).

ex4.c: more complicated: X11 program. Very complicated test in fact
because standard headers are being used ! As for ex1.c, can also be launched
directly as a script: './ex4.c'.

ex5.c: 'hello world' with standard glibc headers.

tcc.c: TCC can of course compile itself. Used to check the code
generator.

tcctest.c: auto test for TCC which tests many subtle possible bugs. Used
when doing 'make test'.

4) Full Documentation

Please read tcc-doc.html to have all the features of TCC.  Additional
information for the Windows port is in tcc-win32.txt.
