Douglas Gregor 37aa4938c8 Introduce a new libclang API, clang_isFileMultipleIncludeGuarded(), 
which determines whether a particular file is actually a header that
is intended to be guarded from multiple inclusions within the same
translation unit.

Douglas Gregor fd4da71343 When determining which preprocessed entities to traverse in libclang, 
take into account the region of interest. Otherwise, we may fail to
traverse some important preprocessed entity cursors. 
Fixes <rdar://problem/8554072>.

Douglas Gregor 2fb99df2c3 When setting the globally-visible declarations for a particular 
identifier, we may have a Sema object but no translation unit scope
(because parsing is finished). In this case, we still need to update
the IdResolver, which might still be used when writing a PCH
containing another PCH (without chaining). This bug manifested as a
failure with precompiled preambles.

Also, add a little environment-variable-sensitive logging for
libclang.

Douglas Gregor 7b02b583b2 When we decide not to reuse a precompiled preamble, clear out the 
previous precompiled preamble completely. Fixes <rdar://problem/8330950>.

Daniel Dunbar 77af1c564e libclang: Execute clang_codeCompleteAt() inside a crash recovery context. 
- Test case is disabled for now, because something isn't write with file
   remapping.

Daniel Dunbar 438c7724f9 Fix a loop overrun in ComputePreamble when the last remapped file was erased, 
and reenable crash recovery test.
 - Reparsing is still very crashy / weird, so I had to sprinkle random code into
   the remapped input to get it to do what I want (i.e., crash!).

Douglas Gregor d9a30af25b When using a precompiled preamble, save the diagnostics produced when 
creating the preamble and "replay" them when reusing the
preamble. Also, fix a thinko in the copying of the preamble when
building the precompiled preamble.

Douglas Gregor 81c000fb6d When remapping a virtual file, also make an entry for the file with 
its absolute path on disk. Also, introduce a fun test for the
precompiled preamble, which almost works...

Douglas Gregor d720daf8bc Make code-completion for Objective-C message sends to "id" work in the 
presence of precompiled headers by forcibly loading all of the
methods we know about from the PCH file before constructing our
code-completion list.

Douglas Gregor 023da0d43a Make sure that we have File IDs for all of the unsaved files before we 
deserialize diagnostics.

Douglas Gregor a75600b7d8 Don't use echo in the Index test, which I hope will work around an intermittent Windows failure

Douglas Gregor aa98ed9a07 Extend clang_createTranslationUnitFromSourceFile() to support creating 
translation units that include unsaved files.

Douglas Gregor 9485bf9538 Extend the CIndex code-completion API to perform code completion 
involving unsaved files, using the -remap-file= functionality recently
added to clang-cc.
