Change int.(<<) and int.(>>) to throw an exception if their second operand is
not in [0, bits_per_int). This brings them into line with the other integer
types.
As a transitional measure, add new functions that provide the old semantics.
library/int.m:
As above.
NEWS:
Announce the above change.
Include the fixed size integer types in the list of reserved type names.
tests/hard_coded/shift_test.m:
Call the legacy versions of the int shift operations.
tests/hard_coded/bitwise_int.{m,exp}:
A new test of bitwise operations for the int type.
(XXX I will add a 32-bit expected output separately.)
tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
Include the new test case.
Do not warn about the use of the obsolete legacy shift operations.
