[Sema] Make FunctionType's TSI use unadjusted argument types

This helps preserve the type-as-written in the AST, which we need for
MSVC mangling.  In particular, we need to preserve the types of array
parameters in function pointer types.

The essence of this change is:
-  QualType ArgTy = Param->getType();
+  QualType ArgTy = Param->getTypeSourceInfo()->getType();

... followed by the adjustment in ActOnFunctionDeclarator().

Revert "[Sema] Make FunctionType's TSI use unadjusted argument types"

This reverts commit r183614.

It broke test/Sema/block-printf-attribute-1.c on non-Windows platforms,
and the fix is not trivial.

Add a test case for blocks taking an array typedef

r183614 was failing because va_list on some platforms is defined in a
similar manner.  This test fails on Windows with r183614 applied.

Fix the parser's updating of the template depth when parsing local templates and late-parsed templates. This is a slight tweak of r180708; It avoids incrementing depth when non-template local classes nested within member templates of local classes are encountered.  
This patch was LGTM'd by Doug http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130506/079656.html and passed the regression tests that normally pass (i.e. excluding many Module and Index tests on Windows that fail regardless)

Revert r183618. 
I ran clang-format on my patch but it seemed to have wreaked havoc with new lines  - might have to do with using it on windows :( will resubmit once i've cleaned this issue up. sorry.

[CodeGen] Move EHScopeStack to CGCleanup.h from CodeGenFunction.h

No functionality change.  CGCleanup.cpp provides the implementation for
EHScopeStack, so it seems more consistent to place the class definition
in CGCleanup.h.

This should also help solve a header ordering problem that I have.

[CodeGen] Make CGCleanup.h include what it now uses

Also move CGCleanup.h to the top of CGCleanup.cpp to verify that
CGCleanup.h really includes what it needs.

Add a new warning, -Wlogical-not-parentheses, to -Wparentheses.

This warning triggers on the logical not of a non-boolean expression on the
left hand side of comparison.  Often, the user meant to negate the comparison,
not just the left hand side of the comparison.  Two notes are also emitted,
the first with a fix-it to add parentheses around the comparison, and the other
to put parenthesis around the not expression to silence the warning.

bool not_equal(int x, int y) {
  return !x == y;  // warn here
}

  return !(x == y);  // first fix-it, to negate comparison.

  return (!x) == y;  // second fix-it, to silence warning.

[analyzer] SATestBuild: Don't require reference results to have logs.

The Logs directory isn't used for testing, so it's filtered out ahead of
time. However, there's then no reason to include it in version control at
all. Don't error if it's not present.

cleanup (address some more review comments for r183474):
- reduce default buffer size to 64, which will still be large enough to
  hold any property names found in the wild.
- get rid of the /*static*/ comments.
