[modules] Instead of storing absolute paths in a .pcm file, store the path to
the root of the module and use paths relative to that directory wherever
possible. This is a step towards allowing explicit modules to be relocated

for good paths in diagnostics, and for appropriate .d output.

Use 32-bit ebp for NaCl64 in a limited case: llvm.frameaddress.
Summary:
Follow up to [x32] "Use ebp/esp as frame and stack pointer":
http://reviews.llvm.org/D4617
In that earlier patch, NaCl64 was made to always use rbp.
That's needed for most cases because rbp should hold a full
64-bit address within the NaCl sandbox so that load/stores
off of rbp don't require sandbox adjustment (zeroing the top
32-bits, then filling those by adding r15).
However, llvm.frameaddress returns a pointer and pointers
are 32-bit for NaCl64. In this case, use ebp instead, which
will make the register copy type check. A similar mechanism
may be needed for llvm.eh.return, but is not added in this change.

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
}
;;

With this patch, the redundant splat operation is removed from the code.

Driver: Objective-C should respect -fno-exceptions
Clang attempted to replicate a GCC bug: -fobjc-exceptions forces
-fexceptions to be enabled. However, this has unintended effects and
other awkard side effects that Clang doesn't "correctly" ape (e.g. it's
impossible to turn off C++ exceptions in ObjC++ mode).
Instead, -f[no]objc-exceptions and -f[no]cxx-exceptions now have an
identical relationship with -f[no]exceptions.

Also this patch replaces all calls to "kmpc_barrier" function by calls of "__kmpc_cancel_barrier" function which provides additional functionality for OpenMP 4.0.
Also, library specific enum OpenMPLocationFlags moved to private section of CGOpenMPRuntime class to make it more independent from library implementation.

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.
