  -----------
  [InstCombine] collectBitParts - add trunc support.

This should allow us to remove the rather limited matchOrConcat fold and just use recognizeBSwapOrBitReverseIdiom.

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

  Log Message:
  -----------
  [clang] RewriteObjCClassMetaData - remove superfluous null pointer check. NFCI.

We've already dereferenced the pointer and no other getClassInterface() calls appear to bother with such a check.
