Summary:
This patch depends on D5501.
Check user name substitution more specifically by specifying it via the new
-config= option.
This also lets clang-tidy tests specify clang-tidy options before the '--'
when using check_clang_tidy_fix.sh.

Summary:
There will be multiple TypeUnits in an unlinked object that will be extracted
from different sections. Now that we have DWARFUnitSection that is supposed
to represent an input section, we need a DWARFUnitSection<TypeUnit> per
input .debug_types section.
Once this is done, the interface is homogenous and we can move the Section
parsing code into DWARFUnitSection.

In addition to __builtin_assume_aligned, GCC also supports an assume_aligned
attribute which specifies the alignment (and optional offset) of a function's
return value. Here we implement support for the assume_aligned attribute by making
use of the @llvm.assume intrinsic.

based on the Function. This is currently used to implement
mips16 support in the mips backend via the existing module
pass resetting the subtarget.
Things to note:
a) This involved running resetTargetOptions before creating a
new subtarget so that code generation options like soft-float
could be recognized when creating the new subtarget. This is
to deal with initialization code in isel lowering that only
paid attention to the initial value.
b) Many of the existing testcases weren't using the soft-float
feature correctly. I've corrected these based on the check
values assuming that was the desired behavior.
c) The mips port now pays attention to the target-cpu and
target-features strings when generating code for a particular
function. I've removed these from one function where the
requested cpu and features didn't match the check lines in
the testcase.

We build a NestedNameSpecifier that records the CXXRecordDecl in which
__super appeared. Name lookup is performed in all base classes of the
recorded CXXRecordDecl. Use of __super is allowed only inside class and
member function scope.

This patch is part of an effort to implement a more generic debugging API, as proposed in http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-July/074656.html, with first part reviewed at http://reviews.llvm.org/D4466. Now adding several new APIs: __asan_report_present, __asan_get_report_{pc,bp,sp,address,type,size,description}, __asan_locate_address. These return whether an asan report happened yet, the PC, BP, SP, address, access type (read/write), access size and bug description (e.g. "heap-use-after-free"), __asan_locate_address takes a pointer and tries to locate it, i.e. say whether it is a heap pointer, a global or a stack, or whether it's a pointer into the shadow memory. If global or stack, tries to also return the variable name, address and size. If heap, tries to return the chunk address and size. Generally these should serve as an alternative to "asan_describe_address", which only returns all the data in text form. Having an API to get these data could allow having debugging scripts/extensions that could show additional information about a variable/expression/pointer. Test cases in test/asan/TestCases/debug_locate.cc and test/asan/TestCasea/debug_report.cc.

No functional change.
I initially thought that pulling the Pat<> into the instruction pattern was
not possible because it was doing a transform on the index in order to convert
it from a per-element (extract_subvector) index into a per-chunk (vextract*x4)
index.
Turns out this also works inside the pattern because the vextract_extract
PatFrag has an OperandTransform EXTRACT_get_vextract{128,256}_imm, so the
index in $idx goes through the same conversion.
The existing test CodeGen/X86/avx512-insert-extract.ll extended in the
previous commit provides coverage for this change.

These are now implemented as two levels of multiclasses heavily relying on the
new X86VectorVTInfo class. The multiclass at the first level that is called
with float or int provides the 128 or 256 bit subvector extracts. The second
level provides the register and memory variants and some more Pat<>s.
I've compared the td.expanded files before and after. One change is that
ExeDomain for 64x4 is SSEPackedDouble now. I think this is correct, i.e. a
bugfix.
(BTW, this is the change that was blocked on the recent tablegen fix. The
class-instance values X86VectorVTInfo inside vextract_for_type weren't
properly evaluated.)

Machine Sink uses loop depth information to select between successors BBs to
sink machine instructions into, where BBs within smaller loop depths are
preferable. This patch adds support for choosing between successors by using
profile information from BlockFrequencyInfo instead, whenever the information
is available.
Tested it under SPEC2006 train (average of 30 runs for each program); ~1.5%
execution speedup in average on x86-64 darwin.

This change does the following:
* Removes the gtest/Makefile recursive-make-based calling strategy
for gtest execution.
* Adds the gtest/do-gtest.py call script.
- This handles finding and calling the Makefiles that really
run tests.
- This script also transforms the test output into something
that Xcode can place a failure marker on when a test fails.
* Modifies the Xcode external build command target for gtest.
It now calls the gtest/do-gtest.py script.
There is still room for improvement on Xcode integration of
do-gtest.py. Essentially the next several lines of error reporting
from the gtest output should be coalesced into a single line so that
Xcode can tell more about the error directly in the editor. Right now
it just puts a red mark and says "failure" but doesn't give any
details.
