[X86][SSE] Regenerate scalar i64 uitofp test Added 32-bit target test llvm-svn: 283883

Use a more efficient lowering of uint64_t --> float that can take advantage of hardware signed integer conversion without having to do a double cast (uint64_t --> double --> float). This is based on the algorithm from compiler_rt's __floatundisf for X86-64. llvm-svn: 115634

; Verify that we are using the efficient uitofp --> sitofp lowering illustrated
; by the compiler_rt implementation of __floatundisf.
