accompanied by a name
and emits an error if a declaration with this name is deserialized from PCH.
This is for testing, to make sure that we don't deserialize stuff needlessly.

print the PCH decls that got deserialized, for testing purposes.

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>).

reparsing an ASTUnit. When saving a preamble, create a buffer larger
than the actual file we're working with but fill everything from the
end of the preamble to the end of the file with spaces (so the lexer
will quickly skip them). When we load the file, create a buffer of the
same size, filling it with the file and then spaces. Then, instruct
the lexer to start lexing after the preamble, therefore continuing the
parse from the spot where the preamble left off.
It's now possible to perform a simple preamble build + parse (+
reparse) with ASTUnit. However, one has to disable a bunch of checking
in the PCH reader to do so. That part isn't committed; it will likely
be handled with some other kind of flag (e.g., -fno-validate-pch).
As part of this, fix some issues with null termination of the memory
buffers created for the preamble; we were trying to explicitly
NULL-terminate them, even though they were also getting implicitly
NULL terminated, leading to excess warnings about NULL characters in
source files.

ASTUnit/CXTranslationUnit. We can't actually use this preamble yet,
however.

reparses an already-parsed translation unit. At the moment it's just a
convenience function, but we hope to use it for performance
optimizations.

-remap-file=from;to
which takes the file "from" and transparently replaces its contents
with the contents of the file "to" from the source manager's
perspective. This is the moral equivalent of
cp from saved
cp to from
<call clang>
cp saved from
rm saved
without all of the pesky file copying.
