When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.
--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
file operations will be abstracted in the future for the reproduction mechanism.
FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

its initial creation/deserialization and store the changes in a chained PCH.
The idea is that the AST entities call methods on the ASTMutationListener to give notifications
of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP

more closely parallel the computation of linkage. This gets us to a state
much closer to what gcc emits, modulo bugs, which will undoubtedly arise in
abundance.

This adds an option to set the _MSC_VER macro without
recompiling. This is very useful when testing compatibility
with the Windows SDK and c++stdlib headers.

doesn't hold. This fix is to increase the loop unrolling count to 4, which experiments show doesn't typically impact
analysis time. The real fix is to modify the IdempotentOperationsChecker to suppress warnings where an analysis point
could be preceded by a point where we gave up due to loop unrolling.

This is for testing, to make sure that we don't deserialize stuff needlessly.

clang_codeCompleteAt(). This uncovered a few issues with the latter:
- ASTUnit wasn't saving/restoring diagnostic state appropriately between
reparses and code completions.
- "Overload" completions weren't being passed through to the client

- lib/gcc/include should not be included. Clang oughta have alternatives. (PR7956)
- Cygwin: /usr/include/w32api should be included. gcc/cygwin does.
- gcc/cygwin uses gcc paths as /usr/lib not /lib. They are same on Cygwin environment, though, We have to take what gcc/cygwin does.
- Cygwin-1.7: Use 4.3.4.
- Cygwin-1.5: Use 4.3.2 for gcc-4.

preambles:
- When we rebuild a precompiled preamble, make sure to disable
skipping anything in the main file; we may have had leftover
preamble-skipping values in the lexer, which leads to very empty
preamble. This is a correctness issue.
- When we rebuild a precompiled preamble, clear out any prior state
in the Diagnostic object. Otherwise, we might think that there
were errors when we were building the preamble itself, and
therefore reject the resulting preamble. This is mainly a
performance issue.
- Don't remove old remappings when digging out the remapping for the
main file. Having the old mappings around does not hurt in the
common case (later remappings will just overwrite them), and is
important when we fail to find a preamble: we don't want to have
removed the remapping, because we'll need it later.

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.

provided when the optimization is disabled. In particular, split
the completion context CCC_Other into two contexts: CCC_Other, which
means that it's an undisclosed context for which any other results are
unwelcome, and CCC_Recovery, which is used in recovery cases.
Since we're now using the completion context within the completion
results builder, make sure that it's always set to something.

slightly penalize "bool".

preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.
