wanglei 70608c24fa [LoongArch] Refactor LoongArchABI::computeTargetABI ...

The previous logic did not consider whether the architectural features
meet the requirements of the ABI, resulting in the generation of
incorrect object files in some cases. For example:

```
llc -mtriple=loongarch64 -filetype=obj test/CodeGen/LoongArch/ir-instruction/fadd.ll -o t.o
llvm-readelf -h t.o
```
The object file indicates the ABI as lp64d, however, the generated code
is lp64s.

The new logic introduces the `feature-implied` ABI. When both target-abi
and triple-implied ABI are invalid, the feature-implied ABI is used.
