  Log Message:
  -----------
  [compiler-rt] Simplify ALIAS() attribute macro

Most uses of ALIAS() are in conjunction with WRAPPER_NAME().

Simplify the code and just make ALIAS() turn its argument into a string
(similar to Linux kernel's __alias macro). This in turn allows removing
WRAPPER_NAME().

  Log Message:
  -----------
  [TSan] Remove unused setjmp definitions

The __interceptor_*setjmp() definitions appear to have been defined for
the purpose of TSAN_INTERCEPT(), but on non-Mac systems, it seems
TSAN_INTERCEPT() isn't even being used anymore for setjmp.

Remove them. Nothing should call them anyway (due to CHECK-fail), so
having the linker fail is better than failing at runtime.

  Log Message:
  -----------
  [compiler-rt] Always use INTERCEPTOR()+ALIAS()+WRAP() to create interceptor alias

Do not open code creation of an interceptor alias to another
interceptor. Instead, use INTERCEPTOR() + ALIAS() + WRAP.
