Fix regression where we aren't passing `-platform_version` to new ld64.lld after {D95204}.
Most of the changes were originally in D95204, but I backed them out due to
test failures on builds which have `CLANG_DEFAULT_LINKER=lld`. The tests are
properly updated in this diff.

In Xcode 11, ld added a new flag called -platform_version that can be used instead of the old -<platform>_version_min flags.
The new flag allows Clang to pass the SDK version from the driver to the linker.
This patch adopts the new -platform_version flag in Clang, and starts using it by default,
unless a linker version < 520 is passed to the driver.

When testing clang that has been compiled with `-DDEFAULT_SYSROOT` set to some path,
some tests would fail. Override sysroot to be empty string for the tests to succeed
when clang is configured with `DEFAULT_SYSROOT`.

The test additions in r329110 are Darwin-specific, as they rely
on a code path that is reachabled when driver is invoked without
-target. Instead of making the old test checks Darwin-specific too,
let's simply split it into two files to ensure that the old
checks are still platform-agnostic. Thanks Chandler for
suggesting this!

if the SDK is newer than the system
This commit improves the driver by making sure that it picks the system version
for the deployment target when the version of the macOS SDK is newer than the
system version.

is true on MSYS bash although this requires: used to disable tests on MSYS bash.
Nevertheless, all tests requiring shell-preserves-root do pass except for
Driver/darwin-sdkroot.c. It will require a patch, either by disabling it on
Windows or by fixing shell-preserves-root to really be true only on MSYS
and making darwin-sdkroot.c its only user.
In any case, all other tests requiring shell-preserves-root do not really require
it so I'm replacing REQUIRES: shell-preserves-root with REQUIRES: shell in two
tests first.

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.
