[NFC] Change the string offsets table tests to generate the object on the fly which enables us to remove the test scripts and object files from the repository. https://reviews.llvm.org/D40914 llvm-svn: 320227 2017-12-09 08:39:53 +08:00			`# RUN: llvm-mc -triple x86_64-unknown-linux %s -filetype=obj -o %t.o`

[DebugInfo][DWARF64] Fix dumping pre-standard .debug_str_offsets.dwo sections. The sizes of offsets in the `.debug_str_offsets.dwo` section depend on the format of compilation or type units referencing them: 4 bytes for DWARF32 units and 8 bytes for DWARF64 ones. The fix uses parsed units to determine the actual size of offsets in the corresponding part of the `.debug_str_offsets.dwo` section.
