Implement -fno-validate-pch at the -cc1 level, which suppresses most
...
of the usual consistency checks used to determine when a precompiled
header is incompatible with the translation unit it's being loaded
into.
Enable this option when loading a precompiled preamble, because the
preamble loader will be performing all of this checking itself. Enable
the preamble-based test now that it's working.
This option is also useful for debugging Clang's PCH
(<rdar://problem/7532213>).

- Stop reading in (and thus deserializing) every declaration in the TU when creating a dependent PCH.
- Switch the storage of a decl context's lexical declarations to a blob containing the IDs instead of a record. This is the only sane way of supporting update records later on.

Don't try to install the __[u]int128_t identifier if it is already installed by PCHReader.
...
Currently, adding it to visible decls of a PCH'ed translation unit has no effect because
adding visible decls before deserialization has no effect (the decls won't be visible).
This will be fixed in a future commit; then it will force deserialization of visible decls, so avoid pointlessly installing it.

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.
