All of the new instructions are still handled mostly by tablegen. I've slightly
refactored the code to drive intrinsic/instruction generation from a master
list of supported variants, so all irregularities have to be implemented in one place only.
The test generation script wmma.py has been refactored in a similar way.

PTX 6.3 requires using ".aligned" in the MMA instruction names.
In order to generate correct name, now we pass current
PTX version to each instruction as an extra constant operand
and InstPrinter adjusts its output accordingly.

Make sure all print statements are compatible with Python 2 and Python3 using
the `from __future__ import print_function` statement.

This is needed for the upcoming implementation of the
new 8x32x16 and 32x8x16 variants of WMMA instructions
introduced in CUDA 9.1.

This way we can support address-space specific variants without explicitly
encoding the space in the name of the intrinsic. Less intrinsics to deal with ->
less boilerplate.
Added a bit of tablegen magic to match/replace an intrinsics with a pointer
argument in particular address space with the space-specific instruction
variant.
Updated tests to use non-default address spaces.

WMMA = "Warp Level Matrix Multiply-Accumulate".
These are the new instructions introduced in PTX6.0 and available
on sm_70 GPUs.
