Andrea Di Biagio 91bdf24cfd [llvm-mca] Account for buffered resources when analyzing "Super" resources. 
This was noticed when working on PR3946.
By construction, a group cannot be used as a "Super" resource. That constraint
is enforced by method `SubtargetEmitter::ExpandProcResource()`.

A Super resource S can be part of a group G. However, method
`SubtargetEmitter::ExpandProcResource()` would not update the number of
consumed resource cycles in G based on S.
In practice, this is perfectly fine because the resource usage is correctly
computed for processor resource units. However, llvm-mca should still check if G
is a buffered resource.
Before this patch, llvm-mca didn't correctly check if S was part of a group that
defines a buffer. So, the instruction descriptor was not correctly set.

For now, the semantic change introduced by this patch doesn't affect any of the
upstream scheduling models. However, it will allow to make some progress on PR3946.
