<pre>
    I was trying to work out how dxil triples work and hit an assert immediately.

Reproduce with `./bin/clang -target dxil--shadermodel6.0-compute -x hlsl /dev/null -o /dev/null`

```
Assertion failed: (EntryList.size() == 1 && "non-lib profiles should only have one entry"), function createEntryMD, file DXILMetadata.cpp, line 296.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
