Fix-forward ASan on Windows.

D127911 deleted llvm.asan.globals. This had a side effect that we no
longer generated the `name` field for the `__asan_global` descriptor
from clang's decscription of the name, but the demangled name from the
LLVM IR. On Linux, this is the same as the clang-provided name. On
Windows, this includes the type, as the name in the IR is the mangled
name.

Attempt #1 to fix-forward the Windows bots by making the tests glob both
sides of the global name, thereby allowing types in the descriptor name.
