Handle %test_debuginfo on a RUN command line.

This set up now allows one to write small test cases to check debug info.
e.g.

; RUN: %clang -O0 -g %s -c -o %t.o
; RUN: %clang %t.o -o %t.out  
; RUN: %test_debuginfo %s %t.out

define i32 @f1(i32 %i) nounwind ssp {
; DEBUGGER: break f1                                                               
; DEBUGGER: r                                                                      
; DEBUGGER: p i                                                                    
; CHECK: $1 = 42                                                                   
entry:
  %i.addr = alloca i32, align 4
...
...
}

It is also possible now to write test cases in c/c++.
The plan is to store these debug info testcases in a separate place.

used in the default function argument as "used". Instead, when we
actually use the default argument, make another pass over the
expression to mark any used declarations as "used" at that point. This
addresses two kinds of related problems:

  1) We were marking some declarations "used" that shouldn't be,
  because we were marking them too eagerly.
  2) We were failing to mark some declarations as "used" when we
  should, if the first time it was instantiated happened to be an
  unevaluated context, we wouldn't mark them again at a later point.

I've also added a potentially-handy visitor class template
EvaluatedExprVisitor, which only visits the potentially-evaluated
subexpressions of an expression. I bet this would have been useful for
noexcept...

preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.
