Read discriminators correctly from object file. Summary: This is the follow-up patch for http://reviews.llvm.org/D19436 * Update the discriminator reading algorithm to match the assignment algorithm. * Add test to cover the new algorithm.

llvm-dwarfdump: Replace -debug-dump=sect option with individual options. As discussed on llvm-dev in http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html this changes the command line interface of llvm-dwarfdump to match the one used by the dwarfdump utility shipping on macOS. In addition to being shorter to type this format also has the advantage of allowing more than one section to be specified at the same time. In a nutshell, with this change $ llvm-dwarfdump --debug-dump=info $ llvm-dwarfdump --debug-dump=apple-objc becomes $ dwarfdump --debug-info --apple-objc Differential Revision: https://reviews.llvm.org/D37714 llvm-svn: 312970

; The intent is to test discriminator 1 generated for both line #4 and #5.
; The instruction sequence in the final binary is:
; line 4 discriminator 0
; line 5 discriminator 0
; line 4 discriminator 1
; line 5 discriminator 1
; We need to ensure that the discriminators for the last two instructions
; are both 1.
