[COMMITTED] alpha: Create __syscall_nocancel entry points

Subject: [COMMITTED] alpha: Create __syscall_nocancel entry points
Authentication-results: sourceware.org; auth=none

Moves the alpha port more in line with x86_64, as fallout from the
recent not-cancel.h change.

The rearrangement preserves the branch prediction, from expected-not-taken
forward branch to expected-taken backward branch.
