6aff5b94ff Make BasicAliasAnalysis a normal AliasAnalysis implementation which 
does normal initialization and normal chaining. Change the default
AliasAnalysis implementation to NoAlias.

Update StandardCompileOpts.h and friends to explicitly request
BasicAliasAnalysis.

Update tests to explicitly request -basicaa.

39e0233734 Remove two uses of the gcc specific 'aligned' attribute. This 
is partly because this attribute caused trouble in the past (the
SmallVector one had to be changed from aligned to aligned(8) due
to causing crashes on i386 for example; in theory the same might
be needed in the Allocator case...).  But it's mostly because
there seems to be no point in special casing gcc here.  Using the
same implementation for all compilers results in better testing.

aafc02daa9 Revert r115099 (adding early jump threading). It's not clear if the benefits are worth the compile time cost.

2511059a16 Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also 
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

e2be7b75b2 Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly. 
The problem was that the test for whether a compiler supports it or not was
inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization
and not needed for correctness, so wrongly thinking a compiler doesn't support
it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not
an optimization: getting it wrong is fatal: it needs to be set based on a
configure test not testing the gcc version.  Since dragonegg has moved to a
different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just
remove this macro.

ca54f909d8 Add a new isSignWrappedSet() method to ConstantRange. 
Fix zeroExtend and signExtend to support empty sets, and to return the smallest
possible result set which contains the extension of each element in their
inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
which contains 63446 members.

f9e09104f1 Make tool_output_file's raw_ostream instance a member variable instead 
of a base class.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.

875b659115 Stop explicitly scheduling domfrontier before the loop passes, 
since none of them use it.  With this, we now only run 
domfrontier (an N^2 analysis) 3 times at clang -O3: once for 
"early" per-function cleanup, once at the start of the
per-function pipeline to support SRoA, and once late because
the EHPrepare class uses it.

EHPrepare needs to stop using it, this is silly and wasteful.
