[PATCH]: A couple of remaining conversions to HOST_WIDE_INT_{,M}1{,U}

[Uros Bizjak]

c/ChangeLog:

2016-07-22  Uros Bizjak  <ubiz...@gmail.com>

    * c-typeck.c: Use HOST_WIDE_INT_1 instead of (HOST_WIDE_INT) 1,

c-family/ChangeLog:

2016-07-22  Uros Bizjak  <ubiz...@gmail.com>

    * c-common.c: Use HOST_WIDE_INT_M1U instead of
    ~(unsigned HOST_WIDE_INT) 0.

Bootstrapped and regression tested on x86_64-linux-gnu, committed to
mainline SVN.

Uros.
