Fix PR79041
As described in PR79041, -mcmodel=large -mpc-relative-literal-loads
may be used to avoid generating ADRP/ADD or ADRP/LDR. However both
trunk and GCC7 may still emit ADRP for some constant pool literals.
Fix this by adding a aarch64_pcrelative_literal_loads check.

(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.

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.

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.

Allocate enough stack space so that the test will work on a system
that does not support split stacks.
This test is actually not very meaningful for gccgo at present, but it
doesn't hurt to keep running it.
