Update code generator to use this attribute and remove NoImplicitFloat target option.
Update llc to set this attribute when -no-implicit-float command line option is used.

build vectors with i64 elements will only appear on 32b x86 before legalize.
Since vector widening occurs during legalize, and produces i64 build_vector 
elements, the dag combiner is never run on these before legalize splits them
into 32b elements.

Teach the build_vector dag combine in x86 back end to recognize consecutive 
loads producing the low part of the vector.

Convert the two uses of TLI's consecutive load recognizer to pass LoadSDNodes
since that was required implicitly.

Add a testcase for the transform.

Changing allocation ordering from r3 ... r0 back to r0 ... r3. The order change no longer make sense after the coalescing changes we have made since then.

Improvements to CXXExprWithTemporaries in preparation for fixing a bug with default arguments that have temporaries.

gcc rather than directly to the linker: gcc will
then modify the linker options it generates (it
will not use --relax for example, incompatible
with -r, as it otherwise would).  This fixes the
sparc build.

we're still missing a mechanism to disable these in strict mode, but 
that's not a new issue.

when generating a coercion for ABI handling purposes.
 - This may only manifest itself when building at -O0, but the practical effect
   is that other arguments may get clobbered.

Make TemplateArgumentListBuilder take an ASTContext (because we're probably going to need it later). Move push_back to the .cpp file. If the passed in template argument is a type, assert that it's canonical.

  - Once we have deduced template arguments for a class template partial
    specialization, we use exactly those template arguments for instantiating
    the definition of the class template partial specialization.
  - Added template argument deduction for non-type template parameters.
  - Added template argument deduction for dependently-sized array types.

With these changes, we can now implement, e.g., the remove_reference
type trait. Also, Daniel's Ackermann template metaprogram now compiles
properly.
