This commit changes the interface of the vld[1234], vld[234]lane, and vst[1234],
vst[234]lane ARM neon intrinsics and associates an address space with the
pointer that these intrinsics take. This changes, e.g.,
<2 x i32> @llvm.arm.neon.vld1.v2i32(i8*, i32)
to
<2 x i32> @llvm.arm.neon.vld1.v2i32.p0i8(i8*, i32)
This change ensures that address spaces are fully taken into account in the ARM
target during lowering of interleaved loads and stores.

Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

Before we unconditinoally forced all users outside the SCoP to use
the preloaded value. However, if the SCoP is not executed due to the
runtime checks, we need to use the original value because it might not
be invariant in the first place.

The XOP shifts just have logical/arithmetic versions and the left/right shifts are controlled by whether the value is positive/negative. Because of this I've added new X86ISD nodes instead of trying to force them to use the existing shift nodes.
Additionally Excavator cores (bdver4) support XOP and AVX2 - meaning that it should use the AVX2 shifts when it can and fall back to XOP in other cases.

specification) to an error. No compiler other than Clang seems to allow this,
and it doesn't seem like a useful thing to accept as an extension in general.
The current behavior was added for PR5957, where the problem was specifically
related to mismatches of the exception specification on the implicitly-declared
global operator new and delete. To retain that workaround, we downgrade the
error to an ExtWarn when the declaration is of a replaceable global allocation
function.
Now that this is an error, stop trying (and failing) to recover from a missing
computed noexcept specification. That recovery didn't work, and led to crashes
in code like the added testcase.

As a first step in the direction of assumed invariant loads (loads
that are not written in some context) we now detect and hoist
definitively invariant loads. These invariant loads will be preloaded
in the code generation and used in the optimized version of the SCoP.
If the load is only conditionally executed the preloaded version will
also only be executed under the same condition, hence we will never
access memory that wouldn't have been accessed otherwise. This is also
the most distinguishing feature to licm.
As hoisting can make statements empty we will simplify the SCoP and
remove empty statements that would otherwise cause artifacts in the
code generation.

The x64 ABI requires that epilogues do not contain code other than stack
adjustments and some limited control flow. However, we'd insert code to
initialize the return address after stack adjustments. Instead, insert
EAX/RAX with the current value before we create the stack adjustments in
the epilogue.
