Summary: As discussed on lldb-dev, this patch moves some LLDB tests into a hierarchy that more closely resembles the commands we use in the LLDB interpreter. This patch should only move tests that use the command interpreter and shouldn't touch any tests that primarily test the SB API. Reviewers: #lldb, jfb, JDevlieghere Reviewed By: #lldb, JDevlieghere Subscribers: dexonsmith, arphaman, JDevlieghere, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D67033 llvm-svn: 370605
