Patch by Brendon Cahoon!

This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.

the failures, and I can't reproduce them :(.

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.

MipsTargetLowering::LowerGlobalTLSAddress. This is necessary to have
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.
