LOG: [Clang][LoongArch] Define more LoongArch specific built-in macros
Define below macros according to LoongArch toolchain conventions [1].
* `__loongarch_grlen`
* `__loongarch_frlen`
* `__loongarch_lp64`
* `__loongarch_hard_float`
* `__loongarch_soft_float`
* `__loongarch_single_float`
* `__loongarch_double_float`
Note:
1. `__loongarch__` has been defined in earlier patch.
2. `__loongarch_arch` is not defined because I don't know how `TargetInfo` can get the arch name specified by `-march`.
3. `__loongarch_tune` will be defined in future.
