04810db83a Allow building lib with gcc/clang
Needed when using ...libtcc1-usegcc=yes in lib/Makefile.

lib/bcheck.c: Add __clang__ for pragma diagnostic
lib/bt-log.c: Add pragma diagnostic as in lib/bcheck.c
lib/builtin.c: Add a lot of alias code to allow building with gcc/clang
lib/stdatomic.c: Same as lib/builtin.c
lib/tcov.c: Avoid clang compiler warning

f89a6f12a7 Fix atomic test_and_set and clear
The __atomic_test_and_set and __atomic_clear code was correct.
They needed locking.
Replaced to code with assembly code.
The changes are in include/stdatomic.h, lib/stdatomic.c, lib/atomic.S
Enabled tests/tests2/124_atomic_counter.c for apple again.

Also moved lib/fetch_and_add.S code to lib/atomic.S.
Removed lib/fetch_and_add.S
Adjusted lib/Makefile

79a8229fb5 Add atomic functions for arm/arm64/riscv
Make code more compatible with gcc. Change
__atomic_store
__atomic_load
__atomic_exchange
__atomic_compare_exchange

Also add (include/stdatomic.h, lib/stdatomic.c):
atomic_thread_fence
atomic_signal_fence
atomic_is_lock_free

And gcc extensions (tcctok.h, tccgen.c, lib/stdatomic.c):
__atomic_fetch_nand
__atomic_and_fetch
__atomic_sub_fetch
__atomic_or_fetch
__atomic_xor_fetch
__atomic_and_fetch
__atomic_nand_fetch

Add new file lib/atomic.S with assembly code for __atomic_compare_exchange_n
for arm/arm64/riscv. Also update lib/Makefile.

Update testcode in 124_atomic_counter and 125_atomic_misc to test new functions.
Also update tests/tests2/Makefile to run tests on arm/arm64/riscv.

48df89e10e stdatomics: tidy & cleanup
- remove any error messages that were just for debugging the
  templates really
- don't use c99 in tcc (array designators etc.)
- remove memory model type (cannot be an own type really)
  and move memory model defines from built-in to stdatomics.h
- apply normal casts to non-pointer atomic_function arguments
- tidy the library support
- add some tests for errors/warnings

Also:
- Makefile: move GIT_HASH stuff from CFLAGS to DEFINES and into
  main section (away from what is included by tests for example)
- tccelf.c/tccgen.c: avoid some warnings with newer GCC
