  -----------
  [Clang][LoongArch] Handle -march/-m{single,double,soft}-float/-mfpu options

This patch adds options -march, -msingle-float, -mdouble-float,
-msoft-float and -mfpu for LoongArch.

Clang options `msingle_float` and `mdouble_float` are moved from
`m_mips_Features_Group` to `m_Group` because now more than targets use
them.

TODO: add -mtune.

  Log Message:
  -----------
  [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.
