libiberty: fix warnings about left shifting a negative value.
GCC PR 66827 reports some problems with left shifting a negative
value:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66827
Of the problems reported only two remain - in libiberty/regex.c:
libiberty/regex.c:6970:11: runtime error: left shift of negative value -1
libiberty/regex.c:7165:4: runtime error: left shift of negative value -1
The patch below fixes these errors by casting the value to be shifted
to unsigned before the shift occurs.
No regressions were found in the libiberty testsuite or bootstrapping
gcc (on an x86_64 target).
