Change macro SHIFT_COUNT_TRUNCATED to target hook TARGET_SHIFT_COUNT_TRUNCATED?

Hello, I have a problem about the definition of SHIFT_COUNT_TRUNCATED. MIPS is a SHIFT_COUNT_TRUNCATED target, and has it defined as 1. While loongson-specific vector insns are not SHIFT_COUNT_TRUNCATED. That means that the macro depends on the machine mode. One simple resolution may be,
