Log:
Revert r314817 "[dwarfdump] Add -lookup option"
The test fails on Linux; see follow-up email on the llvm-commits list.
> Add the option to lookup an address in the debug information and print

>
> Differential revision: https://reviews.llvm.org/D38409
This also reverts the follow-up r314818:
> [test] Fix llvm-dwarfdump/cmdline.test
