      re PR target/79041 (aarch64 backend emits R_AARCH64_ADR_PREL_PG_HI21 relocation despite -mpc-relative-literal-loads option being used)

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.

    • [AArch64, Patch] Generate MLA when multiply + add vector by scalar · 4b40986c 
      (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.

    • syscall: call f?statfs64 on GNU/Linux · 0901429d 
          
    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 · df206c6e 
          
    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.
