  SPIRV: Define runtime libcalls to be (almost) empty

This is a behavior change; previously SPIRV inherited
a default set of calls which seems like a mistake. This
defines a library set with no calls. Add memcpy and memset
as a hack; this avoids PreISelIntrinsicLowering performing
the default expansion. SPIRVPrepareFunctions also calls
the utilities to expand these but the resulting output
is slightly different. The backend specific version
can probably be removed, it for some reason has a larger
output than the default one.
