[Bug target/44072] Use 'add r0, 1' to replace 'cmp r0, -1' in thumb2

It turns out that my original test case matches a conditional move pattern. It
shows another opportunity.

The following code demonstrates a simple compare and branch case

void foo1();
void bar5(int x)
{
  if (x == -1)
    foo1();
}
