Jakob Stoklund Olesen f7c67d9f46 Revert "Clean up in buildbot directories." 
This reverts commit 113814.

This patch was never intended to stay in the repository. If you are reading this
from the future, we apologize for the noise.

Jakob Stoklund Olesen 54481e5948 Clean up in buildbot directories. 
This test created a statements.ll file until about a month ago. Some buildbots
still have this file in their source dir. This is the easiest way to remove the
file on all bots. Then I'll revert.

Chandler Carruth 66ce9651f1 Prevent these tests from dirtying the tree with output files that aren't even 
used for the test.

John McCall a95172baa0 Only run the jump-checker if there's a branch-protected scope *and* there's 
a switch or goto somewhere in the function.  Indirect gotos trigger the
jump-checker regardless, because the conditions there are slightly more
elaborate and it's too marginal a case to be worth optimizing.

Turns off the jump-checker in a lot of cases in C++.  rdar://problem/7702918

Chris Lattner 33919e7450 fix PR7280 by making the warning on code like this: 
int test1() {
  return;
}

default to an error.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Chris Lattner 3eb172a02b Teach sema and codegen about the difference between address of labels, 
which is a common idiom to improve PIC'ness of code using the addr of
label extension.  This implementation is a gross hack, but the only other
alternative would be to teach evalutate about this horrid combination.
While GCC allows things like "&&foo - &&bar + 1", people don't use this
in practice.  This implements PR5131.

Chris Lattner 9842a4dcb1 merge an indirect goto test into statements, add another 
hairier (but nonsensical) example.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc. 
Tests and drivers updated, still need to shuffle dirs.

Chris Lattner 871e0ceffb explicitly document that return statement argument does not necessarily follow the result type of the function. Add testcase.

Chris Lattner a65e1f3b31 Move promoteExprToType from being a static method in SemaExpr.cpp to being 
a method named ImpCastExprToType in Sema.

Use this method to insert implicit casts for case statements from their 
operand type to the condition type of the switch.  This fixes a crash on
test/CodeGen/statements.c, reported by Eli Friedman.
