[AArch64, Patch] Generate MLA when multiply + add vector by scalar

syscall: call f?statfs64 on GNU/Linux
We unconditionally set _FILE_OFFSET_BITS to 64 in configure.ac, so we
should unconditionally call the statfs64 and fstatfs64 functions.
These functions should be available on all versions of GNU/Linux since 2.6.
On 64-bit systems they are aliased to statfs/fstatfs, and on 32-bit
systems they use the 64-bit data structures.

runtime: don't use runtime_lock in __go_get_backtrace_state
If getSiginfo does not know how to determine the PC, it will call
runtime_callers. That can happen in a thread that was started by
non-Go code, in which case the TLS variable g will not be set, in
which case runtime_lock will crash.
Avoid the problem by using atomic operations for the lock. This is OK
since creating a backtrace state is fast and never blocks.
The test case is TestCgoExternalThreadSIGPROF in the runtime package
on a system that getSiginfo doesn't handle specially.
