bpf: fix pseudoc w regs for small modes [PR111029]

In the BPF pseudo-c assembly dialect, registers treated as 32-bits
rather than the full 64 in various instructions ought to be printed as
"wN" rather than "rN".  But bpf_print_register () was only doing this
for specifically SImode registers, meaning smaller modes were printed
incorrectly.

This caused assembler errors like:

  Error: unrecognized instruction `w2 =(s8)r1'

for a 32-bit sign-extending register move instruction, where the source
register is used in QImode.

Fix bpf_print_register () to print the "w" version of register when
specified by the template for any mode 32-bits or smaller.

	PR target/111029

gcc/
	* config/bpf/bpf.cc (bpf_print_register): Print 'w' registers
	for any mode 32-bits or smaller, not just SImode.
