4bb5e48f - [LoongArch] Add codegen support for ILP32D calling convention (#141539)

[LoongArch] Add codegen support for ILP32D calling convention (#141539) This patch adds codegen support for the calling convention defined by the ILP32D ABI, which passes `f64` values using a soft-float mechanism. Similar to RISC-V, it introduces pseudo-instructions to construct an `f64` value from a pair of `i32`s, and to split an `f64` into two `i32` values.
