For values where the result cannot be represented the shift width would be equal to the width of the type, which is undefined. Perform two well-defined shifts instead of one possible undefined shift. * include/bits/hashtable_policy.h (__clp2): Fix calculation for LLP64 targets where sizeof(size_t) > sizeof(long). Avoid undefined shifts of the number of bits in the type. * include/std/bit (__ceil2): Avoid undefined shifts. * testsuite/26_numerics/bit/bit.pow.two/ceil2.cc: Test values with the most signifiant bit set.
