[mips] Add support for isBranchOffsetInRange and use it for MipsLongBranch Add support for this target hook, covering MIPS, microMIPS and MIPSR6, along with some tests. Also add missing getOppositeBranchOpc() cases exposed by the tests. Reviewers: atanasyan, abeserminji, smaksimovic Differential Revision: https://reviews.llvm.org/D46794 llvm-svn: 332446

# NOTE: Assertions have been autogenerated by utils/update_mir_test_checks.py
[mips] Merge MipsLongBranch and MipsHazardSchedule passes MipsLongBranchPass and MipsHazardSchedule passes are joined to one pass because of mutual conflict. When MipsHazardSchedule inserts 'nop's, it potentially breaks some jumps, so they have to be expanded to long branches. When some branch is expanded to long branch, it potentially creates a hazard situation, which should be fixed by adding nops. New pass is called MipsBranchExpansion, it combines these two passes, and runs them alternately until one of them reports no changes were made.
