[Testing] Fix tests that break with read-only checkouts Found with `mount --bind -o ro ...` on Linux. llvm-svn: 367519

Try to organize MachineVerifier tests The Verifier is separate from the MachineVerifier, so move it to a different directory. Some other verifier tests were scattered in target codegen tests as well (although I'm sure I missed some). Work towards using a more consistent naming scheme to make it clearer where the gaps still are for generic instructions. llvm-svn: 354138

# REQUIRES: amdgpu-registered-target
AMDGPU: Fix analyzeBranch failing with pseudoterminators If a block had one of the _term instructions used for gluing exec modifying instructions to the end of the block, analyzeBranch would fail, preventing the verifier from catching a broken successor list. llvm-svn: 347027

# Make sure that mismatched successors are caught when a _term
# instruction is used
# CHECK: *** Bad machine code: MBB exits via unconditional branch but the CFG successor doesn't match the actual successor! ***
