This is part of the efforts adding .gnu_attribute support for PowerPC.
In Clang, an extra metadata field will be added as float-abi to show
current long double format. So backend can emit .gnu_attribute section
data from this metadata.
To avoid breaking existing behavior, the module metadata will only be
emitted when this module makes use of long double.

- Update CodeGenTypeCache to use a single union for all pointers in
address space zero.
- Introduce a UnqualPtrTy in CodeGenTypeCache, and use that (for
example instead of llvm::PointerType::getUnqual) in some places.
- Drop some redundant bit/pointers casts from ptr to ptr.
Partial progress towards replacing `CreateElementBitCast`, as it no
longer does what its name suggests. Either replace its uses with
`Address::withElementType()`, or remove them if no longer needed.

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.
