cmd/compile: accept 'i' suffix orthogonally on all numbers
This change accepts the 'i' suffix on binary and octal integer
literals as well as hexadecimal floats. The suffix was already
accepted on decimal integers and floats.
Note that 0123i == 123i for backward-compatibility (and 09i is
valid).
See also the respective language in the spec change:
