Summary:
Triple components in `XFAIL` lines are tested against the target triple.
Various tests that are expected to fail on big-endian hosts are marked
as being `XFAIL` for big-endian targets. This patch corrects these tests
by having them test against a new `host-byteorder-big-endian` feature.

Prior to this, OptTable::findNearest() thought that the input `--foo`
had an editing distance of 0 from an existing flag `--foo=`, which made
it suggest flags with delimiters more often than flags without one.
After this, it correctly assigns this case an editing distance of 1.

Summary:
This change was part of D46460. However, in the meantime rL341926 fixed the
correctness issue here. What remained was the performance issue in setLoopID
where it would iterate through all blocks in the loop and their successors,
rather than just the predecessor of the header (the later presumably being
much faster). We already have the `getLoopLatches` to compute precisely these
basic blocks in an efficient manner, so just use it (as the original commit
did for `getLoopID`).

In preparation for supporting ILP32 on AArch64, this modifies the SelectionDAG
builder code so that pointers are allowed to have a larger type when "live" in
the DAG compared to memory.

Pointers get zero-extended whenever they are loaded, and truncated prior to
stores.  In addition, a few not quite so obvious locations need updating:

  * A GEP that has not been marked inbounds needs to enforce the IR-documented
    2s-complement wrapping at the memory pointer size. Inbounds GEPs are
    undefined if they overflow the address space, so no additional operations
    are needed.
  * Signed comparisons would give incorrect results if performed on the
    zero-extended values.

This shouldn't affect CodeGen for now, but will become active when the AArch64
ILP32 support is committed.

The fork-siguser.test and fork.test intermittently fail on the AArch64
buildbot. Unfortunately these failures are not reproducible on a similar
machine and seem to fail when the machines are under load. Before
suggesting the tests be marked unsupported for AArch64 we'd like to see
if we can get some more information about the failures to see if it helps
us reproduce. This patch adds --dump-input-on-failure to the FileCheck
commands to see if we can get some more information about the failures.

Summary:
This is a follow up to r355253 and a better fix than the first attempt
which was r359257.

We can't install anything from ${CMAKE_CFG_INTDIR}, because this value
is only defined at build time, but we still must make sure to copy the
headers into ${CMAKE_CFG_INTDIR}/lib/clang/$VERSION/include, because the lit
tests look for headers there.  So for this fix we revert to the
old behavior of copying the headers to ${CMAKE_CFG_INTDIR}/lib/clang/$VERSION/include
during the build and then installing them from the source tree.
