Set symbolizer path in the test environment.

This is needed to get symbolized stack traces when running LLVM tests under (A|M)San.

Add llvm-symbolizer as test dependency.

It is required when building tests with ASan or MSan.

ARM cost model: Add test case to make sure we would notice a change in CodeGen

In r176898 I updated the cost model to reflect the fact that sext/zext/cast on
v8i32 <-> v8i8 and v16i32 <-> v16i8 are expensive.

This test case is so that we make sure to update the cost model once we fix
CodeGen.

Make LTO codegen use a PassManager, rather than a FunctionPassManager, for the
codegen passes. This brings it in to line with clang and llc's codegen setup,
and tidies up the code.

If I understand correctly, adding ModulePasses to a FunctionPassManager is
bogus. It only seems to explode if an added ModulePass depends on a
FunctionPass though, which might be why this code has survived so long.

Fixes <rdar://problem/13386816>.

Reset some of the target options which affect code generation.

This doesn't reset all of the target options within the TargetOptions
object. This is because some of those are ABI-specific and must be determined if
it's okay to change those on the fly.

No functionality change. Rename emitGCNO() to the more sensible
emitProfileNotes(), similar to emitProfileArcs(). Also update its comment.

Also add a comment on Version[4] (there will be another comment in clang later),
and compress lines that exceeded 80 columns.
