Before, we had an unused internal_getpid function for Linux, and a

renamed to internal_getpid, bringing the Linux variant into use.

contains the remainder of sanitizer_common, and is intended to have no

with sanitizer_common.cc, whose libc-dependent portion is moved to
sanitizer_common_libcdep.cc, the first member of the new library.
This split affects the CMake build only. The makefile build continues
to produce the full sanitizer_common library.

[nolibc] Change internal syscall API to remove reliance on libc's errno.
...
This change moves to a model where the error value of a system call is
potentially contained in the return value itself rather than being
implicit in errno. The helper function internal_iserror can be used
to extract the error value from a return value. On platforms other
than Linux/x86_64 this still uses errno, but other platforms are free
to port their error handling to this new model.

[nolibc] Disable the GCC stack protector when building sanitizer runtimes.
...
This is the first in a sequence of changes designed to eliminate the
libc dependency in sanitizer_common. The main motivation for these
changes is to be able to provide an alternative for the current
interceptor-based technique for instrumenting functions in libc.
In this new technique, we compile libc with instrumentation. This has
the potential advantages of being more accurate than interception and
reducing the amount of custom code required for each libc function.
As a side effect of this, we cannot depend on libc in the sanitizer
runtime due to mutual dependency issues.
This change disables the GCC stack protector, which introduces a libc
dependency and is enabled by default in Ubuntu.

Rewrite sw_vers makefile check to avoid error message on Linux.

When building compiler-rt on Linux, the "which sw_vers" check fails and
writes an error message into the build log. Apparently on Solaris "which"
writes the error message to stdout, so that the current test won't even
work properly. As far as I know sw_vers always lives in /usr/bin, so just
check for it there instead of using "which".

This change adds ASan runtime option "strict-init-order" (off by default)
that makes init-order checker bark if global initializer accesses any global from different
translation unit (even if the latter is already initialized). strict init-order checking
doesn't play well with, e.g. LLVM registration machineries, and causes issue

[libsanitizer] Run the callback on a separate stack in StopTheWorld.
...
Currently the callback runs on the caller's stack. If this stack
contains values that have gone out of scope, and we are not super careful, those
values can propagate into global variables (the libc sigaction() in particular
has a side effect that can lead to this). This has caused false negatives in
leak checking code.
Changes: map a separate stack space for the tracer thread. Also, move some
globals into local scope (they had no business being global anyway).

The reason why this simple change is needed is that I am trying to set up a

sanitizers currently.
The default behavior follows exactly what was there before implying that no ones

[asan] Change the way we report the alloca frame on stack-buff-overflow.
...
Before: the function name was stored by the compiler as a constant string
and the run-time was printing it.
Now: the PC is stored instead and the run-time prints the full symbolized frame.
This adds a couple of instructions into every function with non-empty stack frame,
but also reduces the binary size because we store less strings (I saw 2% size reduction).
This change bumps the asan ABI version to v3.
compiler-rt part, llvm part will follow.
Example of report (now):

Split ubsan runtime into three pieces (compiler-rt part):
...
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
sanitizer runtime is present.
* libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
a C++ ABI library, and is always linked in.
* libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
C++ ABI library, and is only linked in when linking a C++ binary.
The Darwin ubsan runtime is unchanged.
