Added files:
lib/libc_r/arch/ia64 _atomic_lock.S
Log:
Add an ia64 atomic lock primitive for libc_r. This is mostly for
completeness and doesn't get us a working libc_r there because libc_r
uses setjmp() and setjmp() cannot be used for context switches on ia64
as-is (or sparc64). Rather than making setjmp/longjmp behave like
the *context() calls, it would be far better to make libc_r use *context()
directly which is what they are for.
