Modify the pragma handlers to accept and use StringRefs instead of IdentifierInfos.
...
When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded).
We can avoid this if we just use StringRefs for the pragmas.
As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified.

This commit 'introduces' a slightly different way to restore the state of the AST object.
It makes PCHDeclReader/PCHDeclWriter friends and gives them access to the private members of the object.
The rationale is to avoid using/modifying the AST interfaces for PCH read/write so that to:
-Avoid complications with objects that have side-effects during creation or when using some setters.
-Not 'pollute' the AST interface with methods only used by the PCH reader/writer
-Allow AST objects to be read-only.

When we know that we are at sub-statement reading (which is all of PCHStmtReader) use the "faster" ReadSubStmt. No functionality change.

Modify the way sub-statements are stored and retrieved from PCH.
...
Before this commit, sub-stmts were stored as encountered and when they were placed in the Stmts stack we had to know what index
each stmt operand has. This complicated supporting variable sub-stmts and sub-stmts that were contained in TypeSourceInfos, e.g.
x = sizeof(int[1]);
would crash PCH.
Now, sub-stmts are stored in reverse order, from last to first, so that when reading them, in order to get the next sub-stmt we just
need to pop the last stmt from the stack. This greatly simplified the way stmts are written and read (just use PCHWriter::AddStmt and
PCHReader::ReadStmt accordingly) and allowed variable stmt operands and TypeSourceInfo exprs.
