This re-commits r226005 with a tweak. The origin attempt failed because
Darwin bot sets up SDKROOT and clang can deduce SDK version from them
after this patch. That broke many driver tests due to the change of
deployment target version. Now the tests should not complain after
r240574.

Summary:
This is a more robust way of figuring out implicit deployment target
from isysroot. It also handles iphone simulator target.

While the test was already requiring shell-preserves-root (such as the
internal shell), it wasn't aware that the MSYS 1.0 env command knows how
to expand root by itself!
From cmd.exe try:
env SDKROOT=/ cmd //c echo %SDKROOT%
And get:
C:/MINGW/MSYS/1.0
To be certain we have a good 'env' program the test now requires a shell.
