[Patch AArch64 obvious] Unify address costs to generic_addrcost_table

The special case address cost tables for Cortex-A57 and qdf24xx are no
different from the generic address cost table. We should just use the
address cost table directly. If this changes in future, a core is welcome
to add new address cost tables.

[Patch AArch64 Obvious] Unify branch costs to generic_branch_cost

All the cores in AArch64 use the pair {1, 3} for their branch costs. As
that is covered by generic_branch_cost, we can just use that directly and
save the tiny amount of redundant code. If in future any core wants to
modify this, they can always add a special-case branch-cost back.

compiler: clean up unresolved placeholders for pointer types

    Add a new helper routine Type::finish_pointer_types that walks through
    the pointer type cache and looks for placeholder types that may have
    been created at some point before conversion of named types, and
    invokes Type::finish_backend() on said placeholders.  This is needed
    to handle cases where the compiler manufactures a pointer type as part
    of lowering, then a placeholder is created for it due to a call to
    Type::backend_type_size(), but there is no explicit reference to the
    type in user code.

[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.

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.
