Sub Tasks

Description
Some new mach nodes which use AVX (3-operands) instructions have prefix 'v' (vsubF_reg) which may confuse them with vector nodes. Do renaming. Also condsolidate avx and vectors macroassembler instructions declaration and definition.

Add float-point vectors loads instructions since SIMD FP execution unit is separate from integer unit in SSE - there is at least one cycle penalty  for moving data between them.
