This patch introduces:
* TypeLoc visiting, which helps a lot in renaming types
* NestedNameSpecifierLoc visiting (through getting them via ASTMatcher at the moment, though, because RecursiveASTVisitor<T>::VisitNestedNameSpecifierLoc isn't implemented), which helps to treat nested names correctly
* better code formatting and refactoring
* bunch of tests

"Incorrect" file name seen on Android whene the main executable is
called "app_process32" (or 64) but the linker specifies the package
name (e.g. com.android.calculator2). Additionally it can be present
in case of some linker bugs.
This CL adds logic to try to fetch the correct file name from the proc
file system based on the base address sepcified by the linker in case
we are failed to load the module by name.

The llvm-cov ‘report' command displays a summary of the coverage of a binary file.
The summary report currently only includes covered regions and covered functions.
This patch adds the coverage of lines in the summary report.

Summary:
The binary layout of prstatus and prpsinfo was wrong.
Some of the member variables where not aligned properly
and others where with a wrong type (e.g. the time related
stuff in prstatus).
I used the structs defined in bfd in binutils to see what the layout
of the elf-core format in these section is.
(https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=bfd/hosts/x86-64linux.h;h=4e420a1f2081dd3b51f5d6b7a8e4093580f5cdb5;hb=master)
Note: those structures are only for x86 64 bit elf-core files
This shouldn't have any impact on the functionality, because
lldb actually uses only a few of the member variables of those structs
and they are with a correct type and alignment.
I found this while trying to add/fix the support for
i386 core files (https://llvm.org/bugs/show_bug.cgi?id=26947)

Summary:
When giving the following command:
% llvm-cov report -instr-profile=default.profraw
llvm-cov will give the following error message:
>llvm-cov report: Not enough positional command line arguments specified!
>Must specify at least 1 positional arguments: See: orbis-llvm-cov report -help
This patch changes the error message from '1 positional arguments'
to '1 positional argument'.

Allowing this variable to be cached makes it possible to repair the MIPS
buildbots in lieu of either fixing the mips64 sanitizer issues or fixing the
detection of mips64 support (which I think was changed by r268977 but didn't
take effect on this buildbot until the last couple days) so that it returns to
not being built on these buildbots.

Run the NVPTX backend over the GPUModule IR and write the resulting assembly
code in a string.
To work correctly, it is important to invalidate analysis results that still
reference the IR in the kernel module. Hence, this change clears all references
to dominators, loop info, and scalar evolution.
Finally, the NVPTX backend has troubles to generate code for various special
floating point types (not surprising), but also for uncommon integer types. This
commit does not resolve these issues, but pulls out problematic test cases into
separate files to XFAIL them individually and resolve them in future (not
immediate) changes one by one.

Just because we can constant fold the result of an instruction does not
imply that we can delete the instruction. It may have side effects.
This fixes PR28655.

This change adds a hasFileAtIndex method. getChildDeclContext can first call this method, and if it returns true it knows it can then lookup the resolved path cache for the given file index. If we hit that cache then we don't even have to call getFileNameByIndex.
Running dsymutil against the swift executable built from github gives a 20% performance improvement without any change in the binary.

The builder prints out the following IR:
\5CCoverageMapping\5COutput\5Ctest\5Cf1.c
The updated test in r276367 expects path separators to be either '/' or
'\\', so it chokes on the unexpected "5C" stuff. I'm not sure what that
is, but I included a kludge that should work around it.

debugserver jGetSharedCacheInfo packet instead of reading
the dyld internal data structures directly. This code is
(currently) only used for ios native lldb's - I should really
move this ObjectFileMachO::GetProcessSharedCacheUUID method
somewhere else, it makes less and less sense being in the
file reader.

We should be able to use `mkdir` without turning on `REQUIRES: shell`.
Moreover, this test should check for a path separator which precedes the
relative filename to make sure that absolute paths are being used.

This checker checks copy and move assignment operators whether they are
protected against self-assignment. Since C++ core guidelines discourages
explicit checking for `&rhs==this` in general we take a different approach: in
top-frame analysis we branch the exploded graph for two cases, where &rhs==this
and &rhs!=this and let existing checkers (e.g. unix.Malloc) do the rest of the
work. It is important that we check all copy and move assignment operator in top
frame even if we checked them already since self-assignments may happen
undetected even in the same translation unit (e.g. using random indices for an
array what may or may not be the same).
This reapplies r275820 after fixing a string-lifetime issue discovered by the
bots.
