of errors and warnings.  This allows us to emit something like this:

2 warnings and 1 error generated.

instead of:

3 diagnostics generated.

This also stops counting 'notes' because they are just follow-on information
about the previous diag, not a diagnostic in themselves.

allowing backend errors to be mapped through clang's 
diagnostics subsystem, including the backend location info.

We now get:

$ clang asm.c -c -o t.o -integrated-as
<inline asm>:1:2: error: unrecognized instruction
        abc incl    %eax
        ^
1 diagnostic generated.

With colors, and correct "# diagnostics generated".

CIndex) and its ownership would not be transferred into the

record (which includes all macro instantiations and definitions). As
with all lay deserialization, this introduces a new external source
(here, an external preprocessing record source) that loads all of the
preprocessed entities prior to iterating over the entities.

The preprocessing record is an optional part of the precompiled header
that is disabled by default (enabled with
-detailed-preprocessing-record). When the preprocessor given to the
PCH writer has a preprocessing record, that record is written into the
PCH file. When the PCH reader is given a PCH file that contains a
preprocessing record, it will be lazily loaded (which, effectively,
implicitly adds -detailed-preprocessing-record). This is the first
case where we have sections of the precompiled header that are
added/removed based on a compilation flag, which is
unfortunate. However, this data consumes ~550k in the PCH file for
Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering
this detailed preprocessing information, so it's too expensive to turn
on by default. In the future, we should investigate a better encoding
of this information.

the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.

The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.

Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.

Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

llvm-svn: 98655

presence or absence of header map arguments when using the precompiled
header would cause Clang to get confused about which headers had
already been included/imported, along with their controlling
macros. The fundamental problem is that the serialization of the
header search information was relying on the UIDs of FileEntry objects
at PCH generation time and PCH load time to be equivalent, which
effectively means that we had to probe the same files in the same
order. Differing header map arguments caused an extra FileEntry
lookup, but it's easy to imagine other minor command-line arguments
triggering this problem.

Header-search information is now encoded along with the
source-location entry for a file, so that we register information
about a file's properties as a header at the same time we create the
FileEntry for that file.

Fixes <rdar://problem/7743243>.
