While C(++) and ObjC are generally formatted the same way and can be
mixed, people might want to choose different styles based on the
language. This patch recognizes .m and .mm files as ObjC and also
implements a very crude detection of whether or not a .h file contains
ObjC code. This can be improved over time.
Also move most of the ObjC tests into their own test file to keep file
size maintainable.

initialization of each array element:
* ArrayInitLoopExpr is a prvalue of array type with two subexpressions:
a common expression (an OpaqueValueExpr) that represents the up-front
computation of the source of the initialization, and a subexpression
representing a per-element initializer
* ArrayInitIndexExpr is a prvalue of type size_t representing the current
position in the loop
This will be used to replace the creation of explicit index variables in lambda
capture of arrays and copy/move construction of classes with array elements,
and also C++17 structured bindings of arrays by value (which inexplicably allow
copying an array by value, unlike all of C++'s other array declarations).
No uses of these nodes are introduced by this change, however.

include-fixer only slightly bloats the size of libclang, but since
libclang has no explicit plugin mechanism it's the only way of getting
this to work. Clang-tidy is already there and so far there weren't many
complaints ;)
This is designed to be easy to remove again if libclang ever grows
proper plugin support.

- Enable lexical binding
- Formatting
- Enable file name completion for the clang-format-executable variable
- Add a missing docstring
- When available, use bufferpos-to-filepos and filepos-to-bufferpos. These functions given more precise mapping than byte-to-position and position-bytes.
- Rename arguments of clang-format-region to match the docstring
- Instead of binding local variables to nil and then assigning them, bind them directly to their values
- Make use of the fact that insert-file-contents returns the number of characters it inserted
- Use cl-destructuring-bind to make the code a bit shorter
- Use standard iteration (dolist) instead of mapc with a lambda, which is more common and shorter
- Remove a message that was most likely only present for debugging purposes

Install the 'clang-cpp' symlink used to spawn the preprocessor. The code
handling this suffix is already included in Driver. FreeBSD is already
creating such a symlink in ports, and a similar one was requested
by Gentoo/FreeBSD team. The goal is to handle software that takes a C
preprocessor via a variable but does not handle passing options
correctly (i.e. 'clang -E' does not work).

Summary:
When building pre-upload hooks using git-clang-format, it is useful to limit the scope to a diff of two commits (instead of from a commit against the working tree) to allow for less false positives in dependent commits.
This change adds the option of specifying two git commits to git-clang-format when using the `--diff` flag, which uses a different strategy to diff (using `git-diff-tree` instead of `git-diff-index`), and runs clang-format against the second commit instead of the working directory.
There is a slight backwards-incompatibility introduced with this change: if a filename matches a branch name or other commit-ish, then `git clang-format <commit> <file>` will no longer work as expected; use `git clang-format <commit> -- <file>` instead.

Remove the relative path hack in scan-build-py that converts a fully qualified
directory name and a fully qualified file path to a relative path before running
the analyzer on a file.
This hack is not needed: the bad interaction with SATestsBuild.py it was
intended to address is actually the same underlying problem that r280768 fixed.
Further, because the hack would always relativize paths, it caused
SATestBuild.py to be unable to properly line up issues when the build system
changed directory and then built a source file in a child directory but used a
fully-qualified path for the source file.

We also need to add ObjCTypeParamTypeLoc. ObjCTypeParamType supports the
representation of "T <protocol>" where T is a type parameter. Before this,
we use TypedefType to represent the type parameter for ObjC.
ObjCTypeParamType has "ObjCTypeParamDecl *OTPDecl" and it extends from
ObjCProtocolQualifiers. It is a non-canonical type and is canonicalized
to the underlying type with the protocol qualifiers.

This commit improves compatibility with the perl version of scan-build.
The perl version of scan-build produces output report directories with
increasing lexicographic ordering. This ordering is relied on by the CmpRuns.py
tool in utils/analyzer when comparing results for build commands with multiple
steps. That tool tries to line up the output directory for each step between
different runs of the analyzer based on the increasing directory name.
The python version of scan-build uses file.mkdtemp() with a time stamp
prefix to create report directories. The timestamp has a 1-second precision.
This means that when analysis of a single build step takes less than a second
the ordering property that CmpRuns.py expects will sometimes not hold,
depending on the timing and the random suffix generated by mkdtemp(). Ultimately
this causes CmpRuns to incorrectly correlate results from build steps and report
spurious differences between runs.
This commit increases the precision of the timestamp used in scan-build-py to
the microsecond level. This approach still has the same underlying issue -- but
in practice analysis of any build step is unlikely to take less than a
millisecond.
