Amazingly this is all that's required.

establish a firm layering separation between these two libraries.

. move compiler-rt to a separate directory so the -L argument only includes compiler-rt (thanks joerg)
. build all clang subdirs
. switches the Minix platform to ELF
. normalizes toolchain invocation

in the context in which it was originally found, the
expression parser now goes hunting for it in all modules
(in the appropriate namespace, if applicable).  This means
that forward-declared types that exist in another shared
library will now be resolved correctly.

Added a test case to cover this.  The test case also tests
"frame variable," which does not have this functionality
yet.

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

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.
