Officially, register X31 does not exist. The code is zeroing out a location
and thus actually needs XZR.
LLVM seems to automatically translate X31 into XZR when compiling the code,
but GCC (tested 7.3.0) refuses to accept the instruction:
../../third_party/crashpad/crashpad/util/misc/capture_context_linux.S: Assembler messages:
../../third_party/crashpad/crashpad/util/misc/capture_context_linux.S:291: Error: operand 1 must be an integer register -- `str x31,[x0,#0xb0]'

uc_mcontext.fpregs is a pointer to the floating point context, but
CaptureContext() doesn't yet capture floating point context.
This error manages to slip by unit tests when run all together, but
fails when CrashpadClient.SimulateCrash is run by itself.

glibc 2.26 defines ucontext_t from a struct ucontext_t while Bionic
and older versions of glibc use a struct ucontext.

Previously, the mac version was under client/ and win under util/win/.
This cl brings them all together under util/misc/ and combines common
test code.
