[PATCH] [DWARF] Add CIE header fields address_size and segment_size when generating dwarf-4

[Keith Walker]

Forgot to subscribe llvm-commits to the phabricator subscriber field,   so repeating the initial summary as a comment in the hope this will make it to the mailing list.

The DWARF-4 specification added 2 new fields in the CIE header called address_size and segment_size.
Create these 2 new fields when generating dwarf-4 CIE entries, print out the new fields when dumping the CIE and update tests
