  Log Message:
  -----------
  [flang] Add LoongArch64 support to lib/Optimizer/CodeGen/Target.cpp

Add LoongArch64 linux target specifics to Target.cpp which is similar to
RISCV-64 in D136547.

For LoongArch, a complex floating-point number, or a structure
containing just one complex floating-point number, is passed as though
it were a structure containing two floating-point reals.

  Log Message:
  -----------
  [flang] Enable LoongArch for x86CompatibleBehavior in floating point flag

Similar to D138503 for RISC-V which fix the flang-OldUnit test failure:

```
.../llvm-project/flang/unittests/Evaluate/real.cpp:504: FAIL:
FlagsToBits(prod.flags) == 0x18, not 0x10
0 0x800001 * 0xbf7ffffe
```

With this patch applied, `check-flang` all pass.
