RISC-V: Fix natural regsize for fixed-vlmax of -march=rv64gc_zve32f

The root cause of those ICEs is vector register size = 32bits, wheras scalar register size = 64bit.
That is, vector regsize < scalar regsize on -march=rv64gc_zve32f FIXED-VLMAX.
So the original natural regsize using scalar register size is incorrect. Instead, we should return minimum regsize between vector regsize and scalar regsize.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_regmode_natural_size): Fix ICE for
FIXED-VLMAX of -march=rv32gc_zve32f.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/bug-4.c: New test.
* gcc.target/riscv/rvv/autovec/bug-5.c: New test.
* gcc.target/riscv/rvv/autovec/bug-6.c: New test.
