This patch fixes an exponential issue in ccmp.c.  When deciding which ccmp
expansion to use, the tree nodes gs0 and gs1 are fully expanded twice.  If
they contain more CCMP opportunities, their subtrees are also expanded twice.
When the trees are complex the expansion takes exponential time and memory.
As a workaround in GCC6 compute the cost of the first expansion early, and
only try the alternative expansion if the cost is low enough.  This rarely
affects real code, eg. SPECINT2006 has identical codesize.

In PR 69577 we have:

      A: (set (reg:V2TI X) ...)
      B: (set (subreg:TI (reg:V2TI X) 0) ...)

X gets allocated to an AVX register, as usual for V2TI.  The problem is
that the movti for B doesn't then preserve the other half of X, even
though the subreg semantics are supposed to guarantee that.

If instead the same value had been set by:

      A': (set (subreg:TI (reg:V2TI X) 16) ...)
      B: (set (subreg:TI (reg:V2TI X) 0) ...)

the subreg in A' would have prevented the use of AVX registers for X,
since you can't directly access the high part.

IMO these are really the same thing.  An alternative way to view it
is that the original sequence is equivalent to:

      A: (set (reg:V2TI X) ...)
      B1: (set (subreg:TI (reg:V2TI X) 0) ...)
      B2: (set (subreg:TI (reg:V2TI X) 16) (subreg:TI (reg:V2TI X) 16))

in which B2 is a no-op and therefore implicit.  The handling ought
to be the same regardless of whether there is an rtl insn that
explicitly assigns to (subreg:TI (reg:V2TI X) 16).

This patch implements that idea.  Hopefully the comments explain
what's going on.

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabihf.
