bpf: correct bpf_print_operand for floats [PR108293]
The existing logic in bpf_print_operand was only correct for integral
CONST_DOUBLEs, and emitted garbage for floating point modes. Fix it so
floating point mode operands are correctly handled.
PR target/108293
gcc/
* config/bpf/bpf.cc (bpf_print_operand): Correct handling for
floating point modes.
gcc/testsuite/
* gcc.target/bpf/double-1.c: New test.
* gcc.target/bpf/double-2.c: New test.
* gcc.target/bpf/float-1.c: New test.
