WebAssembly depends on attributes.h which includes attributes.inc. 
Unless cmake explicitly specifies this dependency, the .inc file 
is sometimes generated after the build tries to use it.

This patch fixes a failure in lnt tests with -verify-machineinstrs option.
When VSX Swap Removal pass swaps two register operands, it did not maintain kill flags associated with operands. This patch swaps flags as well as register number to avoid inconsistent kill flags information.

Summary:
This method was not correct for entries in DWO files as it assumed it
could just add up the CU and DIE offsets to get the absolute DIE offset.
This is not correct for the DWO files, as here the CU offset will
reference the skeleton unit, whereas the DIE offset will be the offset
in the full unit in the DWO file.

Unfortunately, this means that we are not able to determine the absolute
DIE offset using the information in the .debug_names section alone,
which means we have to offload some of this work to the users of this
class.

To demonstrate how this can be done, I've added/fixed the ability to
lookup entries using accelerator tables in DWO files in llvm-dwarfdump.
To make this happen, I've needed to make two extra changes in other
classes:
- made the DWARFContext method to lookup a CU based on the section
  offset public. I've needed this functionality to lookup a CU, and this
  seems like a useful thing in general.
- made DWARFUnit::getDWOId call extractDIEsIfNeeded. Before this, the
  DWOId was filled in only if the root DIE happened to be parsed
  before we called the accessor. Since the lazy parsing is supposed to
  happen under the hood, calling extractDIEsIfNeeded seems appropriate.

When XRay is being built as part of the just built compiler together
with libc++ as part of the runtimes build, we need an explicit
dependency from XRay to libc++ to make sure that the library is
available by the time we start building XRay.

IndVarSimplify sometimes makes transforms basing on users that are trivially dead. In particular,
if DCE wasn't run before it, there may be a dead `sext/zext` in loop that will trigger widening
transforms, however it makes no sense to do it.

This patch teaches IndVarsSimplify ignore the mist trivial cases of that.

This reverts commit r334543.

My understanding is, that commit is intended to make the llvm-build
invocation have a correct "--enable-optional-components" value, but:
- it already has a value: it's quoted in the command line a few lines
  below, and, if I hack llvm-build to print sys.argv, it does look correct:
    -- llvm-build output: ['.../utils/llvm-build/llvm-build',
      '--native-target', 'X86', '--enable-targets', 'X86;ARM;AArch64',
      '--enable-optional-components', '',
      '--write-library-table',
      '.../build/tools/llvm-config/LibraryDependencies.inc',
      '--write-cmake-fragment', '.../build/LLVMBuild.cmake']
- the " " string seems to evaluate to TRUE in CMake (*sigh*), so this
  basically force-enables LLVM_USE_INTEL_JITEVENTS, regardless of the
  value of the option.
  On Darwin, JITEvents is not supported, so this bypasses that OS check
  but is guaranteed to fail later.

Previously we were whitelisting in instructions based on their SchedRW value. With the masked store instructions explicitly removed via NotMemoryFoldable, we don't seem to need this check anymore.

When running with linker GC (`-opt:ref`), defined imported symbols that
are referenced but then dropped by GC end up with their `Location`
member being nullptr, which means `getChunk()` returns nullptr for them
and attempting to call `getChunk()->getOutputSection()` causes a crash
from the nullptr dereference. Check for `getChunk()` being nullptr and
bail out early to avoid the crash.
