[Mips] Fix clang crashes when compiling a variadic function while targeting mips3 (#130558)
issue reason:
Because mips3 has the feature 'FeatureGP64Bit', when target mips3
process function `writeVarArgRegs`, the result of `getGPRSizeInBytes` is
8 and the result of `GetVarArgRegs` is `Mips::A0, Mips::A1, Mips::A2,
Mips::A3`. This would generate `gpr64 = COPY $a1` which should be `gpr64
= COPY $a1_64`.
Also when process `CC_Mips_FixedArg`, mips would CCDelegateTo
`CC_MipsO32_FP`. In fact, it should CCDelegateTo `CC_MipsN`.
Fix #98716.
