Morning,
I've noticed that 256bit vector support has been added to the D frontend during
the development stages of 2.060 whilst was looking around in druntime core.

Is anyone willing to object if I raise a pull request to add 64bit Vector
support in the D frontend too for architectures that support? This includes
i386/x86_64 using MMX extensions, and ARM using NEON extensions.
Not sure how well DMD would cope with the type in it's backend though, but can
always reject it in its backend with an error.
64 bit MMX extensions for x86 are, as far as I can tell, quite obsolete. The
CPUs support those instructions for backwards compatibility, but I cannot see
any reason for D to add new support for it.
