svn r145378 inadvertently changed the destination for the Embedded target
in the makefile. Add a "/Developer" suffix to DSTROOT to compensate.

So far all of configure tests have been run against the default SDK and
architecture, regardless of what is actually being built. We've gotten
lucky until now. <rdar://problem/11112479>

This also avoids emitting the information twice, which led to code bloat. On i386-linux-Release+Asserts
with all targets built this change shaves a whopping 1.3 MB off clang. The number is probably exaggerated
by recent inliner changes but the methods were already enormous with the old inline cost computation.
The DWARF reg -> LLVM reg mapping doesn't seem to have holes in it, so it could be a simple lookup table.
I didn't implement that optimization yet to avoid potentially changing functionality.
There is still some duplication both in tablegen and the generated code that should be cleaned up eventually.

First small step toward modeling multi-register multi-pressure. In the
future, register units can also be used to model liveness and
aliasing.

Use an explicit comparator instead of the default.
The sets are sorted, but not using the default comparator. Hopefully,
this will unbreak the Linux builders.

TableGen emits lists of sub-registers, super-registers, and overlaps. Put
them all in a single table and use a SequenceToOffsetTable to share
suffixes.

This is similar to the StringToOffsetTable we use to produce string
tables, but it can be used for other sequences than strings, and it
eliminates entries for suffixes.

The arm_neon intrinsics can create virtual registers from the DPair
register class which allows both even-odd and odd-even D-register pairs.
This fixes PR12389.

* Removed test/lib/llvm.exp - it is no longer needed
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
left in the test suite so this code is no longer required. test/lit.cfg is
now much shorter and clearer
* Removed a lot of duplicate code in lit.local.cfg files that need access to
the root configuration, by adding a "root" attribute to the TestingConfig
object. This attribute is dynamically computed to provide the same
information as was previously provided by the custom getRoot functions.
* Documented the config.root attribute in docs/CommandGuide/lit.pod

This is in braces so that it doesn't conflict with the existing %p.
It uses braces instead of parens because parens would have to be
regex-escaped.

We can simply confirm the handle released to open it with EXCLUSIVE. Attempting renaming was bad.
Disable win32file at ImportError. Thanks to Francois to let me know.
FIXME: Could we report warning or notification if win32file were not found?

In previous case,
RUN: foo -o %t
RUN: FileCheck < %t
RUN: bar -o %t
2nd read handle might prevent manipulation of 3rd %t in bar, to remove and rename.

We cannot limit the concatenated instruction names to 64K. ARM is
already at 32K, and it is easy to imagine a target with more
instructions.
