Enhance both TargetLibraryInfo and SelectionDAGBuilder so that the latter can use the former to prevent the formation of libm SDNode's when  -fno-builtin is passed.

Filter "sink to" candidate blocks sooner. This avoids unnecessary computation to determine whether the block dominates all uses or not.

call16(__tls_get_addr) emitted instead of got_disp(__tls_get_addr) when the

Don't explicitly marked libm rounding ops as legal on SSE4.1/AVX.  There don't seem to be patterns for these, so I don't know why they were marked legal in the first place.

- Modify lowering of global TLS address nodes.
- Modify isel of ThreadPointer.
- Wrap target global TLS address nodes that are operands of loads with WrapperPIC. 
- Remove Mips-specific DAG nodes TlsGd, TprelHi and TprelLo, which can be
  substituted with other existing nodes.

Teach SelectionDAG to match more calls to libm functions onto existing SDNodes.  Mark these nodes as illegal by default, unless the target declares otherwise.

umbrella headers in the sense that all of the headers within that
directory (and eventually its subdirectories) are considered to be
part of the module with that umbrella directory. However, unlike
umbrella headers, which are expected to include all of the headers
within their subdirectories, Clang will automatically include all of
the headers it finds in the named subdirectory.

The intent here is to allow a module map to trivially turn a
subdirectory into a module, where the module's structure can mimic the
directory structure.

pointer to make the result of an expression.  LLDB now
dumps the ivars of the Objective-C object and all of
its parents.  This just required fixing a bug where we
didn't distinguish between Objective-C object pointers
and regular C-style pointers.

Also added a testcase to verify that this continues to
work.

Many of the SSE patterns should not be selected when AVX is available. This led to the following code in X86Subtarget.cpp

  if (HasAVX)
    X86SSELevel = NoMMXSSE;

This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected.
However, this breaks instructions which do not have AVX variants.

The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX().
Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change.

However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case,
the prefetch instructions. rdar://10538297
