[AArch64, Patch] Generate MLA when multiply + add vector by scalar
(On behalf of jackson.woodruff@arm.com)
This merges vector multiplies and adds into a single mla instruction
when the multiplication is done by a scalar.
typedef int __attribute__((vector_size(16))) vec;
vec
mla1(vec v0, vec v1, int v2)
{
return v0 + v1 * c;
}
Now generates:
mla1:
fmov s2, w0
mla v0.4s, v1.4s, v2.s[0]
This is also done for the identical case for a multiply followed by a
subtract of vectors with an integer operand on the multiply.

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.
