Split SelectionDAGISel::IsLegalAndProfitableToFold to
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.
This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

Check in the first big step of rewriting DAGISelEmitter to
produce a table based matcher instead of gobs of C++ Code.
Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).
The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp). When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.
There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.

Functions explicitly marked inline will get an inlining threshold slightly
more aggressive than the default for -O3. This means than -O3 builds are
mostly unaffected while -Os builds will be a bit bigger and faster.
The difference depends entirely on how many 'inline's are sprinkled on the
source.
In the CINT2006 suite, only these tests are significantly affected under -Os:
