cygwin has llvm-dwarfdump problems and isn't paying attention to the
specific xfail there.
s390x isn't matching for an unknown reason.

Sorry for the breakage.
For now, it will fail in two ways:
1. To fail for targeting x86_64-mingw32.
<stdin>:131:8: note: possible intended match here
0x30830a0100000002 3 0 1 0 0 is_stmt
2. To fail not to find the target x86.
llc: : error: unable to get target for 'x86_64-unknown-unknown',
see --version and --triple.

these is very much off and is more than just the branch
from this bug incorrect:
Address Line Column File ISA Discriminator Flags
------------------ ------ ------ ------ --- ------------- -------------
0x30830a0100000002 3 0 1 0 0 is_stmt
0x30830a0100000008 3 0 1 0 0 is_stmt end_sequence

llc doesn't generate nodes for unconditional fall-through branches for targets
without FastISel implementation (X86 has it, but can be disabled by
"-fast-isel=false") in SelectionDAGBuilder::visitBr().
So for line 4 in the following testcase
1: void foo(int i){
2: switch(i){
3: default:
4: break;
5: }
6: return;
7: }
there is no corresponding line in .debug_line section, and a debugger
cannot set a breakpoint at line 4.
Fix this by always emitting a branch when we're not optimizing and add a
testcase to ensure that there's code on every line we'd want to break.
