New patch add some comments and update docs for this new usage.

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).
