Kuba Mracek aa4d9e2a66 [sanitizer] Refactor how assembly files are handled
This renames ASM_TSAN_SYMBOL and ASM_TSAN_SYMBOL_INTERCEPTOR to just ASM_SYMBOL and ASM_SYMBOL_INTERCEPTOR, because they can be useful in more places than just TSan. Also introduce a CMake function to add ASM sources to a target.

Kuba Brecka f94bb99adc [tsan] Port tsan_rtl_amd64.S to OS X to add support for setjmp/longjmp
This patch ports the assembly file tsan_rtl_amd64.S to OS X, where we need several changes:

* Some assembler directives are not available on OS X (.hidden, .type, .size)
* Symbol names need to start with an underscore (added a ASM_TSAN_SYMBOL macro for that).
* To make the interceptors work, we ween to name the function "_wrap_setjmp" (added ASM_TSAN_SYMBOL_INTERCEPTOR for that).
* Calling the original setjmp is done with a simple "jmp _setjmp".
* __sigsetjmp doesn't exist on OS X.

Adhemerval Zanella 2f7f5e3535 [compiler-rt] [tsan] Enable intercept setjmp/longjmp for AArch64
This patch adds assembly routines to enable setjmp/longjmp for aarch64
on linux.  It fixes:

 * test/tsan/longjmp2.cc
 * test/tsan/longjmp3.cc
 * test/tsan/longjmp4.cc
 * test/tsan/signal_longjmp.cc

I also checked with perlbench from specpu2006 (it fails to run
with missing setjmp/longjmp intrumentation).
