    In preparation for upgrading libgo to the 1.9 release, this
    approximately incorporates https://golang.org/cl/37661 and
    https://golang.org/cl/38351.
    
    CL 37661 changed the gc compiler such that the select statement simply
    returns an integer which is then used as the argument for a switch.
    Since gccgo already worked that way, this just adjusts the switch code
    to look like the gc switch code by removing the explicit case index
    expression and calculating it from the order of calls to selectsend,
    selectrecv, and selectdefault.
    
    CL 38351 simplifies the channel code by not passing the unused channel
    type descriptor pointer.

This includes a change to LRA.  Previously the code was:

    if (sclass == NO_REGS && dclass == NO_REGS)
      return false;
  #ifdef SECONDARY_MEMORY_NEEDED
    if (SECONDARY_MEMORY_NEEDED (sclass, dclass, GET_MODE (src))
  #ifdef SECONDARY_MEMORY_NEEDED_MODE
        && ((sclass != NO_REGS && dclass != NO_REGS)
            || GET_MODE (src) != SECONDARY_MEMORY_NEEDED_MODE (GET_MODE (src)))
  #endif
        )
      {
        *sec_mem_p = true;
        return false;
      }
  #endif

in which the positioning of the second ifdef meant that defining
SECONDARY_MEMORY_NEEDED_MODE to its default value was not a no-op:
without a definition, we would consider using secondary reloads for
mem<-reg and reg<-mem reloads even if the secondary memory has the
same mode as the original mem, while defining it would avoid this.
The latter behaviour seems correct.

The default is different for reload and LRA.  For LRA the default is
to use the original mode, while reload promotes smaller-than-word
integral modes to word mode:

  if (GET_MODE_BITSIZE (mode) < BITS_PER_WORD && INTEGRAL_MODE_P (mode))
    mode = mode_for_size (BITS_PER_WORD,
                          GET_MODE_CLASS (mode), 0).require ();

Some of the ports that have switched to LRA seemed to have
SECONDARY_MEMORY_NEEDED_MDOEs based on the old reload definition,
and still referred to the reload.c:get_secondary_mem function in
the comments.  The patch just keeps them as-is.

This patch changes pr62178.c so that it now scans
for two `ldr`s, one into an `s` register, instead
of a `ld1r` as before. Also add a scan for an mla
instruction.

The `ld1r` was needed when this should have generated
a mla by vector. Now that we can generate an mla by
element instruction and can load directly into the
simd register, it is cheaper to not do the ld1r
which needlessly duplicates the single element used
across the whole vector register.

As Alexander pointed out in the thread starting at [1] the sort_by_bitpos sorting function
was behaving badly when we had multiple stores at the same position.  He fixed that (thanks!)
but we can do better by not returning zero when the bitpositions are equal but by falling back
to comparing the order the stores appear in, which is guaranteed to be unique (barring other
bugs elsewhere).

This patch does that.

Bootstrapped and tested on aarch64-none-linux-gnu.

Coprocessor intrinsic tests in gcc.target/arm/acle test whether
__ARM_FEATURE_COPROC has the right bit defined before calling the
intrinsic. This allows to test both the correct setting of that macro
and the availability and correct working of the intrinsic. However the
__ARM_FEATURE_COPROC macro is no longer defined for ARMv8-A since
r249399.

This patch changes the testcases to skip that test for ARMv8-A and
ARMv8-R targets.  It also fixes some irregularity in the coprocessor
effective targets:
- add ldcl and stcl to the list of instructions listed as guarded by
  arm_coproc1_ok
- enable tests guarded by arm_coproc2_ok, arm_coproc3_ok and
  arm_coproc4_ok for Thumb-2 capable targets but disable for Thumb-1
  targets.
