Adrian Prantl 5def96f7e9 Reapply: Teach SROA how to update debug info for fragmented variables. 
This reapplies r225379.

ChangeLog:
- The assertion that this commit previously ran into about the inability
  to handle indirect variables has since been removed and the backend
  can handle this now.
- Testcases were upgrade to the new MDLocation format.
- Instead of keeping a DebugDeclares map, we now use
  llvm::FindAllocaDbgDeclare().

Original commit message follows.

Debug info: Teach SROA how to update debug info for fragmented variables.
This allows us to generate debug info for extremely advanced code such as

 typedef struct { long int a; int b;} S;

 int foo(S s) {
   return s.b;
 }

which at -O1 on x86_64 is codegen'd into

 define i32 @foo(i64 %s.coerce0, i32 %s.coerce1) #0 {
   ret i32 %s.coerce1, !dbg !24
 }

with this patch we emit the following debug info for this

 TAG_formal_parameter [3]
   AT_location( 0x00000000
                0x0000000000000000 - 0x0000000000000006: rdi, piece 0x00000008, rsi, piece 0x00000004
                0x0000000000000006 - 0x0000000000000008: rdi, piece 0x00000008, rax, piece 0x00000004 )
                AT_name( "s" )
                AT_decl_file( "/Volumes/Data/llvm/_build.ninja.release/test.c" )

Thanks to chandlerc, dblaikie, and echristo for their feedback on all
previous iterations of this patch!
