Improvements to ARM assembler tests
No functional changes. Got myself bitten in r223113 when adding support for
modified immediate syntax (regressions reported by joerg@britannica.bec.de,
fixes in r223366 and r223381). Our assembler tests did not cover serveral
different syntax variants. This patch expands the test coverage to check for
the following cases:
1. Modified immediate operands may be expressed with expressions, as in #(4 * 2)
instead of #8.
2. Modified immediate operands may be _optionally_ prefixed by a '#' symbol or a
'$' symbol.
3. Certain instructions (e.g. ADD) support single input register variants;
[ADD r0, #mod_imm] is same as [ADD r0, r0, #mod_imm].
4. Certain instructions have aliases which convert plain immediates to modified
immediates. For an example, [ADD r0, -10] is not valid because -10 (in two's
complement) cannot be encoded as a modified immediate, but ARMInstrInfo.td
defines an alias which can transform this into a [SUB r0, 10].

[X86] Avoid introducing extra shuffles when lowering packed vector shifts.
When lowering a vector shift node, the backend checks if the shift count is a
shuffle with a splat mask. If so, then it introduces an extra dag node to
extract the splat value from the shuffle. The splat value is then used
to generate a shift count of a target specific shift.
However, if we know that the shift count is a splat shuffle, we can use the
splat index 'I' to extract the I-th element from the first shuffle operand.
The advantage is that the splat shuffle may become dead since we no longer
use it.
Example:
;;
define <4 x i32> @example(<4 x i32> %a, <4 x i32> %b) {
%c = shufflevector <4 x i32> %b, <4 x i32> undef, <4 x i32> zeroinitializer
%shl = shl <4 x i32> %a, %c
ret <4 x i32> %shl

Consider subregs when calling MI::registerDefIsDead for phys deps
The scheduling dependency graph is built bottom-up within each scheduling
region, and ScheduleDAGInstrs::addPhysRegDeps is called to add output/anti
dependencies, based on physical registers, to the SUs for instructions
based on those that come before them.
In the test case, we start before post-RA scheduling with a block that looks
like this:
...
INLINEASM <...
andc $0,$0,$2
stdcx. $0,0,$3
bne- 1b
> [sideeffect] [mayload] [maystore] [attdialect], $0:[regdef-ec:G8RC], %X6<earlyclobber,def,dead>, $1:[mem], %X3<kill>, $2:[reguse:G8RC], %X5<kill>, $3:[reguse:G8RC], %X3, $4:[mem], %X3, $5:[clobber], %CC<earlyclobber,imp-def,dead>, <<badref>>
...
%X4<def,dead> = ANDIo8 %X4<kill>, 1, %CR0<imp-def,dead>, %CR0GT<imp-def>
...
%R29<def> = ISEL %R3<undef>, %R4<kill>, %CR0GT<kill>
where it is relevant that %CC is an alias to %CR0, and that %CR0GT is a
subregister of %CR0. However, for post-RA scheduling, no dependency was added
to prevent the INLINEASM from being scheduled in between the ANDIo8 and the
ISEL (which communicate via the %CR0GT register).
In ScheduleDAGInstrs::addPhysRegDeps, when called for the %CC operand, we'd
iterate over all of its aliases (which include %CC itself and also %CR0), and
look for previously-encountered defs of those registers. We'd find the ANDIo8,
but decide not to add a dependency between the INLINEASM and the ANDIo8 because
both the INLINEASM's def of %CC is dead, and also the ANDIo8 def of %CR0 is
dead. This ignores, however, that ANDIo8 has a non-dead def of %CR0GT, a
subregister of %CR0, and thus a dependency still must exist.
To fix this problem, when calling registerDefIsDead on the SU with the def, we
also check all subregisters for possible non-dead defs, and add the dependency
if any are found.
Fixes PR21742.

Kill any python test script that takes more than 5 minutes
There is at least one test that hangs on the Linux debian buildbot.
When that test hangs, the buildbot kills dosep which loses all test
results. This change kills just the hung test and should let us see
which test is hanging. This is useful for that test and any others
in the future which start hanging.

[ASan, LSan] Improve tracking of thread creation.
In the current scheme of things, the call to ThreadStart() in the child
thread is not synchronized with the parent thread. So, if a pointer is passed to
pthread_create, there may be a window of time during which this pointer will not
be discoverable by LSan. I.e. the pthread_create interceptor has already
returneed and thus the pointer is no longer on the parent stack, but we don't
yet know the location of the child stack. This has caused bogus leak reports
(see http://llvm.org/bugs/show_bug.cgi?id=21621/).
This patch makes the pthread_create interceptor wait until the child thread is
properly registered before returning.

CMake: build DLLs in the right directory and include them in the 'install' target (PR21719)
When CMake builds a dynamic library on Windows, the .dll file's location is
determined by the RUNTIME_OUTPUT_DIRECTORY, which we were previously not
setting.
This means for example that clang_rt.asan_dynamic-i386.dll will get built
and installed in the same directory as the corresponding .lib file,
instead of being built in the bin/ directory and not installed at all.
