Bug 77586, and previously
<https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, reports
ia64-elf failing to build because of float128_type_node being NULL,
but being used by the back end for __float128.

The global float128_type_node is only available conditionally, if
target hooks indicate TFmode is not only available as a scalar mode
and of the right format, but also supported in libgcc.  The back-end
support, however, expects the type always to be available for
__float128 even if the libgcc support is missing.

Although a target-specific node could be restored in the case where
libgcc support is missing, it seems better to address the missing
libgcc support.  Thus, this patch enables TFmode soft-fp in libgcc
globally for all ia64 targets.  Support for XFmode in libgcc (that is,
for libgcc2.c XFmode functions, not soft-fp) is also enabled for all
ia64 targets so that ia64 no longer needs to define the
TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P hook.

I've confirmed that ia64-elf builds cc1 with this patch and it passes
-fself-test.  I have not otherwise tested the patch.  It's plausible
that ia64-elf and ia64-freebsd might work as-is, but ia64-vms probably
needs further changes, by someone familiar with VMS shared libraries,
to implement an equivalent of ia64/t-softfp-compat in that case
(avoiding conflicts between __divtf3 from soft-fp and the old alias
for __divxf3).

    Change the compiler to use the new routines. Drop the separation of
    small and large values when sending on a channel. Allocate the select
    struct on the stack. Remove the old C implementation of channels. Adjust
    the garbage collector for the new data structure.
    
    Bring in part of the tracing code, enough for the channel code to call.
    
    Bump the permitted number of allocations in one of the tests in
    context_test.go. The difference is that now receiving from a channel
    allocates a sudog, which the C code used to simply put on the
    stack. This will be somewhat better when we port proc.go.

	PR tree-optimization/77901
	* tree-ssa-reassoc.c (optimize_range_tests_var_bound): Only optimize
	if ranges[i].exp is SSA_NAME when looking for >= and only when
	ranges[i].exp is NULL or SSA_NAME when looking for the other
	comparison.

	* gcc.c-torture/compile/pr77901.c: New test.
