tests: fix RISC-V failures and adjust transmute-scalar.rs target

Browse Source 
Resolve several ./x test failures on RISC-V caused by ABI and codegen
differences. Update multiple codegen-llvm tests for compatibility, and
explicitly set the target for transmute-scalar.rs to x86_64 to ensure
consistent behavior across hosts.
