Summary: Merge branch 'master' into 1758_6
Test Plan:
No functionality change. Run "make check" and run test-suite.
Because our servers are not yet running again I have not yet run test-suite.
I will further review myself before submission.

Summary:
Included this file which is needed to enable tablegen generated functionality
for fast mips-isel
Test Plan:
This has no visible functionality by itself but just adding the include

Rather than requiring ARM support for the ELF tests (which is odd), move the
tests that require ARM into a subdirectory to use lit to disable them if the
support is not present. Play this game to prevent disabling the ELF tests on
the Windows build bots as they have caught issues in the past with interactions
between various platforms.

GAS documents the .type directive as having an optional comma following the key
symbol name when using the STT_<TYPE_IN_UPPER_CASE> form. However, it treats
the comma as optional in all cases. This makes the IAS support both forms of
inputs. Furthermore, the prefixed forms take either the upper case name or the
lower case alias.
The tests are split into two separate sets as the hash character serves as a
comment character on x86, which is tested in the second set by using arm-elf
which uses the at symbol as a comment character.

COFF/PE, so the relocation model is never static. Loosen the assertion
accordingly. The relocation can still be emitted properly, as it will be
converted to an IMAGE_REL_ARM_ADDR32 which will be resolved by the loader
taking the base relocation into account. This is necessary to permit the
emission of long calls which can be controlled via the -mlong-calls option in
the driver.

Add a brief explanation of the data section layout for the unwind data that the
Windows on ARM EH models. This is simply to provide a rough idea of the layout
of the code involved in the decoding of the unwinding. Details on the involved
data structures are available in the associated support header. The bulk of it
is related to printing out the byte-code to help validate generation of WoA EH.

Now the scheduler updates a node's ready time as soon as it is
scheduled, before releasing dependent nodes. There was a reason I
didn't do this initially but it no longer applies.
A53 is in-order and was running into an issue where nodes where added
to the readyQ too early. That's now fixed.
This also makes it easier for custom scheduling strategies to build
heuristics based on the actual cycles that the node was scheduled at.
The only impact on OOO (sandybridge/cyclone) is that ready times will
be slightly more accurate. I didn't measure any significant regressions.

Prevent the early elimination of sections in the object writer. There may be
references to the section itself by other symbols, which may potentially not be
possible to resolve. ML (Visual Studio's Macro Assembler) also seems to retain
empty sections.
The elimination of symbols and sections which are unused should really occur at
the link phase. This will not cause any change in the resulting binary, simply
in the generated object files.
The adjustments to the other unit tests account for the fluctuating section
index caused by the appearance of sections which were previously discarded.

* Section association cannot use just the section name as many
sections can have the same name. With this patch, the comdat symbol in
an assoc section is interpreted to mean a symbol in the associated
section and the mapping is discovered from it.
* Comdat symbols were not being set correctly. Instead we were getting
whatever was output first for that section.
A consequence is that associative sections now must use .section to
set the association. Using .linkonce would not work since it is not
possible to change a sections comdat symbol (it is used to decide if
we should create a new section or reuse an existing one).
This includes r210298, which was reverted because it was asserting
on an associated section having the same comdat as the associated
section.

These checks were accidentally skipping the 0x prefix in the hex
offsets, then cunningly ignoring the prefix in the use of those captured
values.
Except in the case of the unit length, where the match was only matching
the leading '0' before the x in the 0x prefix, then matching that
against the length. We can't actually express the length association
here, as the length field in the Compile Unit header does not include
the length field itself, but the length field in the pubnames section
/does/ include the size of the length field in the Compile Unit header -
so the two numbers are actually 4 bytes different. Just skip matching
that.

This was added to test that DW_AT_GNU_pubnames used sec_offset in DWARF4
and data4 in DWARF3 and below. Since then we've updated
DW_AT_GNU_pubnames to be a flag, rather than a section offset anyway.
Granted this still differs between DWARF 3 and DWARF 4
(FORM_flag_present versun FORM_flag) but it doesn't seem worthwhile
testing that codepath again here. It's covered adequately in many other
test cases.
And while I'm here, don't hardcode the byte size of the compile unit -
it's not relevant to this test and just makes it brittle if/when
anything changes in the way this CU is emitted.

This patch fixes a couple of lowering issues for little endian
PowerPC. The code for lowering BUILD_VECTOR contains a number of
optimizations that are only valid for big endian. For now, we disable
those optimizations for correctness. In the future, we will add
analogous optimizations that are correct for little endian.
When lowering a SHUFFLE_VECTOR to a VPERM operation, we again need to
make the now-familiar transformation of swapping the input operands
and complementing the permute control vector. Correctness of this
transformation is tested by the accompanying test case.

If we have common uses on separate paths in the tree; process the one with greater common depth first.

clang's own CMake setup handles this as of r210308.
The CMAKE_CROSSCOMPILING special-case will no longer be hard-coded. This was
clearly site-specific to someone's local configuration and should be passed in
at configure time if needed with e.g. -DLIBXML2_LIBRARIES=... (the libxml2
target I tried here doesn't even support liblzma so it's *way* off).

Alias with unnamed_addr were in a strange state. It is stored in GlobalValue,
the language reference talks about "unnamed_addr aliases" but the verifier
was rejecting them.
It seems natural to allow unnamed_addr in aliases:
* It is a property of how it is accessed, not of the data itself.
* It is perfectly possible to write code that depends on the address
of an alias.
This patch then makes unname_addr legal for aliases. One side effect is that
the syntax changes for a corner case: In globals, unnamed_addr is now printed
before the address space.

We extended the .section syntax to allow multiple sections with the
same name but different comdats, but currently we don't make sure that
the output section has that comdat symbol.
That happens to work with the code llc produces currently because it looks like
.section secName, "dr", one_only, "COMDATSym"
.globl COMDATSym
COMDATSym:
....
but that is not very friendly to anyone coding in assembly or even to
llc once we get comdat support in the IR.
This patch changes the coff object writer to make sure the comdat symbol is
output just after the section symbol, as required by the coff spec.
