llvmpipe: fix blending with half-float formats

The fact that we flush denorms to zero breaks our half-float
conversion and blending. This patches enables denorms for
blending. It's a little tricky due to the llvm bug that makes
it incorrectly reorder the mxcsr intrinsics:

dri megadriver_stub: add compatibility for older DRI loaders

To help the transition period when DRI loaders are being updated
to support the newer __driDriverExtensions_foo mechanism,
we populate __driDriverExtensions with the extensions returned
by __driDriverExtensions_foo during a library contructor
function.

We find the driver foo's name by using the dladdr function
which gives the path of the dynamic library's name that
was being loaded.
