Summary: debug info generates duplicate label
Product: libraries

c++ testcase
The attached delta-reduced test program produces bad assembly when built with
debug info:
$ llvm-g++ y.c -g
/tmp/cc5eEOy7.s: Assembler messages:
/tmp/cc5eEOy7.s:79: Error: symbol `.Llabel11' is already defined
$ llvm-g++ y.c
/usr/lib/../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status
Not sure if it's llvm-gcc's fault for producing bad debug info in the first
place or a backend bug, so I'm filing it as a backend bug.
This happens on x86-64 linux.
