Fix ASan's Noinst unit tests
...
We currently skip all "Noinst" unit tests on OS X, which was probably caused when we removed the "allow_reexec" flag. The MaybeReexec function fails to re-execute when the runtime is linked statically, because there is no dylib to use. This patch adds an explicit DisableReexec function that is used from asan_noinst_test.cc and the runtime then doesn't try to re-execute.

[ASan] Move the SIGSEGV/SIGBUS handling to sanitizer_common

This change is a part of refactoring intended to have common signal handling behavior in all tools.
This particular CL moves InstallSignalHandlers() into sanitizer_common (making it InstallDeadlySignalHandlers()), but doesn't enable default signal handlers for any tool other than ASan.
