[lto] Fix bootstrap failure

[Doug Kwan (關振德)]

Thanks for fixing that.  Unfortunately enum is not always unsigned:

C99 6.7.2.2 (3)

Each enumerated type shall be compatible with an integer type. The
choice of type is
implementation-defined,99) but shall be capable of representing the
values of all the
members of the enumeration. The enumerated type is incomplete until
after the}that
terminates the list of enumerator declarations.

Removing the test is fine but it will not catch an error if some
version of gcc picks a signed type to represent the enums.  Maybe we
should cast it to unsigned first and then test like:

gcc_assert ((unsigned) reason < CIF_N_REASON);
