TargetSchedModel now always delegates to MCSchedModel the computation of
instruction latency and reciprocal throughput.
No functional change intended.

This should fix the problem reported by the lld buildbots:
- Builder lld-x86_64-darwin13, Build #19782
- Builder lld-perf-testsuite, Build #1419

The goal is to make the reciprocal throughput computation accessible through the
MCSchedModel interface. This is particularly important for llvm-mca because it
can only query the MCSchedModel interface.
No functional change intended.

The goal is to make the latency information accessible through the MCSchedModel
interface. This is particularly important for tools like llvm-mca that only have
access to the MCSchedModel API.
This partially fixes PR36676.

`MCSchedModel` is large. Make `MCSchedModel::GetDefaultSchedModel()`
return by-reference instead of by-value, so we can store a pointer in
`MCSubtargetInfo::CPUSchedModel` instead of a copy.
Note: since `MCSchedModel` is POD, this doesn't create a static
constructor.
