RISC-V: Fix program logic errors caused by data truncation on 32-bit host for zbs, such as i386
Correct logic on 64-bit host:
...
bseti a5,zero,38
bseti a5,a5,63
addi a5,a5,-1
and a4,a4,a5
...
Wrong logic on 32-bit host:
...
li a5,64
bseti a5,a5,31
addi a5,a5,-1
and a4,a4,a5
...
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_build_integer_1): Change
1UL/1ULL to HOST_WIDE_INT_1U.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/zbs-bug.c: New test.
