Use the somewhat semantic term "split dwarf" it more matches what's going on and makes a lot of the terminology in comments make more sense. llvm-svn: 169758

; RUN: llc -split-dwarf=Enable -O0 %s -mtriple=x86_64-unknown-linux-gnu -filetype=obj -o %t
Add some first skeleton work for the DWARF5 Fission proposal. Emit part of the compile unit CU and start separating out information into the various sections that will be pulled out later. WIP. llvm-svn: 169061

; Check that the skeleton compile unit contains the proper attributes:
; This DIE has the following attributes: DW_AT_comp_dir, DW_AT_stmt_list,
; DW_AT_low_pc, DW_AT_high_pc, DW_AT_ranges, DW_AT_dwo_name, DW_AT_dwo_id,
; DW_AT_ranges_base, DW_AT_addr_base.
Refactor out the abbreviation handling into a separate class that controls each of the abbreviation sets (only a single one at the moment) and computes offsets separately as well for each set of DIEs. No real function change, ordering of abbreviations for the skeleton CU changed but only because we're computing in a separate order. Fix the testcase not to care. llvm-svn: 169793
