[SystemZ] Improve handling of inline asm constraints. The "{=v0}" constraint did not result in the expected error message in the abscence of the vector facility, because 'v0' matches as a string into the AnyRegBitRegClass in common code. This patch adds checks for vector support in case of "{v" and soft-float in case of "{f" to remedy this.
