d: Merge upstream dmd 09db0c41e, druntime e68a5ae3.
* New core.math.toPrec templates have been added as an intrinsic.
Some floating point algorithms, such as Kahan-Babuska-Neumaier
Summation, require rounding to specific precisions. Rounding to
precision after every operation, however, loses overall precision in
the general case and is a runtime performance problem.
Adding these functions guarantee the rounding at required points in
the code, and document where in the algorithm the requirement exists.
* Support IBM long double types in core.internal.convert.
* Add missing aliases for 64-bit vectors in core.simd.
* RUNNABLE_PHOBOS_TEST directive has been properly integrated into the
D2 language testsuite.
