and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.

SrcMgrDiagHandler, we can improve clang diagnostics for inline asm:
instead of reporting them on a source line of the original line,
we can report it on the correct line wherever the string literal came
from. For something like this:

void foo() {
  asm("push %rax\n"
      ".code32\n");
}

we used to get this: (note that the line in t.c isn't helpful)

t.c:4:7: error: warning: ignoring directive for now
  asm("push %rax\n"
      ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

now we get:

t.c:5:8: error: warning: ignoring directive for now
      ".code32\n"
       ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

Note that we're pointing to line 5 properly now.

cookie argument to the SourceMgr diagnostic stuff.  This cleanly separates
LLVMContext's inlineasm handler from the sourcemgr error handling 
definition, increasing type safety and cleaning things up.

Take care of special characters while creating named MDNode name to hold function specific local variable's info.
This fixes radar 8653152. I am checking in testcase as a separate check-in.

Add simple counter to count no. of basic blocks without any line number information. At -O0, these basic block coule cause less than optimial debugging experience.

emit an alignment for comm.  THis will hopefully fix PR8198.

If FE forgot to provide a file name (usually it uses "stdin" as name in such situation) then make one up to ensure that debug info is not malformed.
