I want to install the upstream stuff mentioned in the lkgr.json file in the
`upstream` folder. How do I do that through the EMSDK? Running the "emsdk
list" command gives me this output:

I don't understand which one to get if I want upstream LLVM from the LLVM
GitHub repo. Also, I was thinking it might be `sdk-wasm-master-64bit` and
therefore tried to install that, but I got stuck on building Clang.
Please note that I what I mean by it being stuck on building Clang is that
it failed with an error:
Build failed due to exception!
> Working directory: C:/emsdk/clang/upstream\build_master_vs2017_64
> Command '['C:\\Program Files (x86)\\Microsoft Visual
> Studio\\2017\\Community\\MSBuild/15.0/Bin/amd64\\MSBuild.exe', '/t:Build',
> '/p:Configuration=Release', '/p:Platform=x64', '/nologo',
> '/verbosity:minimal', 'LLVM.sln']' returned non-zero exit status 1
> Installation failed!
Another question I want to ask is this: is it possible to just have the
EMSDK download the necessary files for the SDKs or tools I want and then
use CMake to build them myself?
Speaking of LLVM/Clang, if that SDK has the upstream version, it should
have WebAssembly as a target to build rather than an experimental target
because in LLVM 9 it's not an experimental target anymore and is included
by default (`-DLLVM_TARGETS_TO_BUILD=all` is the default setting, and
WebAssembly is included under "all"). But I noticed that the EMSDK uses
the setting `-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly`. Doesn't
that mean it's an older version of LLVM? Also, is it vanilla LLVM built to
target WebAssembly, or is it Fastcomp?
I want to get the lkgr stuff. And preferably I want EMSDK to use my own
global installations of Java, Python and Node. If possible. Please help.
Thanks in advance.
