Otherwise, it's possible for some __config_site macros not to be

LegacyInlinerBase::doFinalization runs removeDeadFunctions() to remove bar but
the new PM inliner doesn't. Improve the test to use llvm-nm -U.

Update the clang complex builtins for OpenMP to use the
correct max function from either __nv_* or __ocml_*.

These logically belong together since it's a base commit plus
followup fixes to less common build configurations.

The patches are:

Revert "CfgInterface: rename interface() to getInterface()"

This reverts commit a74fc481.

Revert "Wrap CfgTraitsFor in namespace llvm to please GCC 5"

This reverts commit f2a06875.

Revert "Try to make GCC5 happy about the CfgTraits thing"

This reverts commit 03a5f7ce.

Revert "Introduce CfgTraits abstraction"

This reverts commit c0cdd22c.

This reverts commit 848a68a0.

* Still rough edges that need more sugar but the bones are there. Notes left in the test case for things that can be improved.
* Does not actually yield custom OpViews yet for traversing. Will rework that in a followup.

I do not exactly like the use of a negative predicate to
enable instructions' support. Change HasNoMadMacF32Insts
with HasFmaLegacy32.

When porting libc++ to embedded systems, it can be useful to drop support
for localization, which these systems don't implement or care about.

Shrink `FileEntryRef` to the size of a pointer, by having it directly
reference the `StringMapEntry` the same way that `DirectoryEntryRef`
does. This makes `FileEntryRef::FileEntryRef` private as a side effect
(`FileManager` is a friend!).

There are two helper types added within `FileEntryRef`:

- `FileEntryRef::MapValue` is the type stored in
  `FileManager::SeenFileEntries`. It's a replacement for
  `SeenFileEntryOrRedirect`, where the second pointer type has been
  changed from `StringRef*` to `MapEntry*` (see next bullet).
- `FileEntryRef::MapEntry` is the instantiation of `StringMapEntry<>`
  where `MapValue` is stored. This is what `FileEntryRef` has a pointer
  to, in order to grab the name in addition to the value.

Merge prefixes where possible, use 'X86' instead of 'X32' (which we try to only use for gnux32 triple tests).

Add VSUMS/VSUMX/VFSUM/VMAXS/VMAXX/VFMAX/VRAND/VROR/VRXOR isntructions.
Add regression tests too.

This patch changes MergeBlockIntoPredecessor to skip the call to
RemoveRedundantDbgInstrs, in effect partially reverting D71480 due to
some compile-time issues spotted in LoopUnroll and SimplifyCFG.

The call to RemoveRedundantDbgInstrs appears to have changed the
worst-case behavior of the merging utility. Loosely speaking, it seems
to have gone from O(#phis) to O(#insts).

It might not be possible to mitigate this by scanning a block to
determine whether there are any debug intrinsics to remove, since such a
scan costs O(#insts).

So: skip the call to RemoveRedundantDbgInstrs. There's surprisingly
little fallout from this, and most of it can be addressed by doing
RemoveRedundantDbgInstrs later. The exception is (the block-local
version of) SimplifyCFG, where it might just be too expensive to call
RemoveRedundantDbgInstrs.

Make it possible to use a relative path in command script import to the
location of the file being sourced. This allows the user to put Python
scripts next to LLDB command files and importing them without having to
specify an absolute path.

To enable this behavior pass `-c` to `command script import`. The
argument can only be used when sourcing the command from a file.
