commit 8821d2f0960cb0b2a2cf6373ab76d92f1a948ae1
Author: Feng Wang <wangfeng@eswincomputing.com>

RISC-V:Optimize the MASK opt generation
The corresponding MASK and TARGET will be automatically generated.
Accoring to Kito's advice, using "MASK(name) Var(other_flag_name)"
to generate MASK and TARGET MACRO automatically.
This patch improve the MACRO generation of MASK_* and TARGET_*.
Due to the more and more riscv extensions are added, the default target_flag
is full.
Before this patch,if you want to add new MACRO,you should define the
MACRO in the riscv-opts.h manually.
After this patch, you just need two steps:
1.Define the new TargetVariable.
2.Define "MASK(name) Var(new_target_flag).
