revisiting this section when I implement declaration matching

the shift type was needed one place, the shift count
type another.  The transform in 123555 had the same
problem.

(add Y, (sete  X, 0)) -> cmp X, 1; adc  0, Y
(add Y, (setne X, 0)) -> cmp X, 1; sbb -1, Y
(sub (sete  X, 0), Y) -> cmp X, 1; sbb  0, Y
(sub (setne X, 0), Y) -> cmp X, 1; adc -1, Y

for
  unsigned foo(unsigned a, unsigned b) {
    if (a == 0) b++;
    return b;
  }
we now get:
  foo:
    cmpl  $1, %edi
    movl  %esi, %eax
    adcl  $0, %eax
    ret
instead of:
  foo:
    testl %edi, %edi
    sete  %al
    movzbl  %al, %eax
    addl  %esi, %eax
    ret

inconsistent with the type that the builtin *should* have, forget
about the builtin altogether: we don't want subsequence analyses,
CodeGen, etc., to think that we have a proper builtin function.

C is protected from errors here because it allows one to use a
library builtin without having a declaration, and detects inconsistent
(re-)declarations of builtins during declaration merging. C++ was
unprotected, and therefore would crash.

Fixes PR8839.

classes, categories, protocols, and class extensions, where the
methods and properties of these entities would be inserted into the
DeclContext in an ordering that doesn't necessarily reflect source
order. The culprits were Sema::ActOnMethodDeclaration(), which did not
perform the insertion of the just-created method declaration into
the DeclContext for these Objective-C entities, and
Sema::ActOnAtEnd(), which inserted all method declarations at the
*end* of the DeclContext. 

With this fix in hand, clean up the code-completion actions for
property setters/getters that worked around this brokenness in the AST.

Fixes <rdar://problem/8062781>, where this problem manifested as poor
token-annotation information, but this would have struck again in many
other places.

Fix PR 8199.  This patch prepends the build tool dir to LLVM programs
being tested.  This ensures that we test the tools just built and not
some random tools that might happen to be in the user's PATH.  This
makes LLVM testing much more stable and predictable.
