`CGBuilderTy::CreateElementBitCast()` no longer does what its name suggests.
Remove remaining in-tree uses by one of the following methods.
* drop the call entirely
* fold it to an `Address` construction
* replace it with `Address::withElementType()`
This is a NFC cleanup effort.

This commit breaks up CodeGen/TargetInfo.cpp into a set of *.cpp files,
one file per target. There are no functional changes, mostly just code moving.
Non-code-moving changes are:
* A virtual destructor has been added to DefaultABIInfo to pin the vtable to a cpp file.
* A few methods of ABIInfo and DefaultABIInfo were split into declaration + definition
in order to reduce the number of transitive includes.
* Several functions that used to be static have been placed in clang::CodeGen
namespace so that they can be accessed from other cpp files.
