Original message:
Add a funciton to get the segment name of a section.
On MachO, sections also have segment names. When a tool looking at a .o file
prints a segment name, this is what they mean. In reality, a .o has only one
anonymous, segment.
This patch adds a MachO only function to fetch that segment name. I named it
getSectionFinalSegmentName since the main use for the name seems to be infor
the linker with segment this section should go to.
The patch also changes MachOObjectFile::getSectionName to return just the
section name instead of computing SegmentName,SectionName.

Have clang_getSpellingLocation() use the same logic as DiagnosticRenderer for plowing through macros.
This fixes a subtle bug reported in <rdar://problem/
12584554> where a double-nested
macro could lead to an incorrect fixit location with live issues.
This fix also uncovers a bunch of subtle bugs in our indexer test cases which
are now fixed (mostly around source ranges for attributes).

This is the libclang patch providing minimal API to
use clang's formatter. Currently, formatter is used
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.

Verify bundle flag consistency when setting them.
Now that the bundle flag aware APIs are all in place, it is possible to
continuously verify the flag consistency.

Verify bundle flags for consistency in MachineVerifier.
The new bidirectional bundle flags are redundant, so inadvertent bundle

Disable ARM partial flag dependency optimization at -Oz
To not over constrain the scheduler for ARM in thumb mode, some optimizations for code size reduction, specific to ARM thumb, are blocked when they add a dependency (like write after read dependency).
Disables this check when code size is the priority, i.e., code is compiled with -Oz.

Don't allow the automatically updated MI flags to be set directly.
The bundle-related MI flags need to be kept in sync with the neighboring
instructions. Don't allow the bulk flag-setting setFlags() function to
change them.
Also don't copy MI flags when cloning an instruction. The clone's bundle
flags will be set when it is explicitly inserted into a bundle.

Better support for constructor initializers.
We used to format initializers like this (with a sort of hacky implementation):
Constructor()
: Val1(A),
Val2(B) {
and now format like this (with a somewhat better solution):
Constructor()
: Val1(A), Val2(B) {
assuming this would not fit on a single line. Also added tests.
As a side effect we now first analyze whether an UnwrappedLine needs to be
split at all. If not, not splitting it is the best solution by definition. As
this should be a very common case in normal code, not exploring the entire
solution space can provide significant speedup.
