Derek Bruening 34913f3beb [esan|wset] Ensure SIGSEGV is not blocked
Summary:
Adds interception of sigprocmask and pthread_sigmask to esan so that the
working set tool can prevent SIGSEGV from being blocked.  A blocked SIGSEGV
results in crashes due to our lazy shadow page allocation scheme.

Adds new sanitizer helper functions internal_sigemptyset and
internal_sigismember.

Adds a test to workingset-signal-posix.cpp.
