[issue27078] Make f'' strings faster than .format: BUILD_STRING opcode?

Thank you for your review Eric. I considered passing NULL, but as Antti said, it is already used for space separated concatenation. PyUnicode_New(0, 0) is the obvious way to get an empty string, and I think it is fast enough. If this affects performance we can add additional microoptimization later.
