re PR tree-optimization/90883 (Generated code is worse if returned struct is unnamed)
After add --param max-inline-insns-size=1 all target will remove the
redundant store at dse1, except some targets like AArch64 and MIPS will
expand the struct initialization into loop due to CLEAR_RATIO.
Tested on cross compiler of riscv32, riscv64, x86, x86_64, mips, mips64,
aarch64, nds32 and arm.
