Subject: [PATCH] Support --sysroot= for ${arch}-windows-msvc targets
I think it is possible to use the same rule for msvc targets with
--target= and --sysroot=
See Repository:
https://github.com/trcrsired/windows-msvc-sysroot
Add sysroot support for msvc
MSVC.cpp needs getDriver before using D
add stl in parser for -stdlib=
Add Vcruntime to runtime list and unwind list
MSVC add default runtime lib type and default unwind lib type
add a msvc sysroot test
use %S instead of /foo
Fix test for msvc-sysroot
Also add a pesudo implementation for WebAssembly and
maybe Microsoft STL could be ported to more targets in the future
Fix the toggle of wasm that prevents -stdlib=stl passed into
