It's violate coding guideline in LLVM coding standard[1], because the the initialization order is nondeterministic and that might increase the launch time of programs.
However these variables are only used to cache query result, so we can move these variables into the function,, that which resolve both issue: 1. initialized in deterministic order, 2. Initialized that when the first time used.

This patch does the same thing as D125886 did.
- Use `Overloaded` rather than `Mangled`.
- Use `Prototype` or `Desc` rather than `Seq`, it's not just a string
sequence.

This NFC patch is splited from D111617.
Using llvm::ArrayRef rather than llvm::SmallVector, ArrayRef is more generic
interface that could accept both llvm::ArrayRef and llvm::SmallVector.

This patch is preparation for D111617, use class/struct/enum rather than char/StringRef to present internal information as possible, that provide more compact way to store those info and also easier to serialize/deserialize.
And also that improve readability of the code, e.g. "v" vs TypeProfile::Vector.

We add a new clang library called `clangSupport` for putting those utils which can be used in clang table-gen and other clang component.
We tried to put that into `llvm/Support`, but actually those stuffs only used in clang* and clang-tblgen, so I think that might be better to create `clang/Support`
* clang will used that in https://reviews.llvm.org/D111617.
