[PATCH] D62457: Frontend: Create basic CompilerInstanceBuilder

[Duncan P. N. Exon Smith via Phabricator via cfe-commits]

dexonsmith added a reviewer: rsmith.
dexonsmith added a child revision: D62458: Frontend: Add CompilerInvocation and DiagnosticsEngine to the builder.

This sketches out the beginning of a `CompilerInstanceBuilder`.  For now
it just handles PCHContainerOps and InMemoryModuleCache, which are
already handled by the `CompilerInstance` constructor.

Subsequent commits will incrementally replace `CompilerInstance::set*`
and `CompilerInstance::create*` mutators with builder methods,
simplifying construction and possibly clarifying some lifetimes.
