Richard Henderson d8cbc13ab6 alpha: Fix end-of-count checks in strncmp 
This routine suffered a similar problem as stxncpy in needing to
bias a potentially very large unsigned number with wraparound.
This exposed a secondary problem where we didn't properly handle
end-of-count condition for the second string input resulting in
stratcliff failures.

Richard Henderson 8e2f4e971f alpha: Fix [BZ #13718] 
The routines expect to be able to bias the count by a small number.
If the count is near -1ull, the count will overflow.  Since we cannot
use the whole 64-bit address space, bound the count to LONG_MAX.

Aurelien Jarno 116ff9ad18 alpha: fix corner cases in ceil, floor, rint. 
Partial revert of bebc49030c. Even with the revert, ceil and floor are
still faster than libcpml's equivalent.

Fixes bug 5350.

Richard Henderson a9374d8174 alpha: Adjust the libc_cv_alpha_hidden_gprel test for gcc 4.5. 
GCC 4.5 was able to tell that BAR was read-only and zero, and
elided the load.  Which caused the pattern match to fail.
