reduced testcase (from gcc.target/riscv/rvv/vsetvl/imm_switch-1.c)
I have a strong feeling of reporting this before, but I can't find the original
PR. Sorry for the dup, if I searched poorly.
This probably needs RTL checking enabled.
Compiler output:
$ riscv64-unknown-linux-gnu-gcc -march=rv32gcv -mabi=ilp32e testcase.c
during RTL pass: expand
testcase.c: In function 'f_n':
testcase.c:2:6: internal compiler error: RTL check: expected code 'const_int',
