    c: Handle conversion from bool to capability pointer
    
    We were checking explicitly for INTEGER_TYPE, relax this to
    INTEGRAL_TYPE_P instead to also handle converting from booleans and
    enums to capability pointers.
    
    gcc/c/ChangeLog:
    
            * c-convert.c (convert): Handle converting from enums and
            booleans to capability pointers.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/aarch64/morello/conv-bool-ptr.c: New test.
