The fold code also expanded cabs(x+yi) to fsqrt(x*x+y*y) when optimising
for speed.  tree-ssa-math-opts.c has this transformation too, but unlike
the fold code, it first checks whether the target implements the sqrt
optab.  The patch simply removes the fold code and keeps the
tree-ssa-math-opts.c logic the same.

gcc.dg/lto/20110201-1_0.c was relying on us replacing cabs
with fsqrt even on targets where fsqrt is itself a library call.
The discussion leading up to that patch suggested that we only
want to test the fold on targets with a square root instruction,
so it would be OK to skip the test on other targets:

        https://gcc.gnu.org/ml/gcc-patches/2011-07/msg01961.html
        https://gcc.gnu.org/ml/gcc-patches/2011-07/msg02036.html

The patch does that using the sqrt_insn effective target.

It's possible that removing the tree folds renders the LTO trick
unnecessary, but since the test was originally for an ICE, it seems
better to leave it as-is.

This patch adds a pass that collects information that is common to
all uses of an SSA name X and back-propagates that information up
the statements that generate X.  The general idea is to use the
information to simplify instructions (rather than a pure DCE) so
I've simply called it gimple-ssa-backprop.c, to go with
tree-ssa-forwprop.c.

At the moment the only use of the pass is to remove unnecessary
sign operations, so that it's effectively a global version of
fold_strip_sign_ops.  I'm hoping it could be extended in future
to record which bits of an integer are significant.  There are
probably other potential uses too.

A later patch gets rid of fold_strip_sign_ops.

    The fix for golang/go#11541 made the assertion that getting an invalid
    Numeric_constant after evaluating an invalid constant must result in
    an error in a binary expression.  However, a Numeric_constant can be
    invalid if it is unset, which occurs when either operand cannot be
    converted to the right type.  These errors are issued after the
    Numeric_constant is lowered.
    
    Fixes golang/go#12615.
