DWARF: space-optimize loc. descr. for integer literals on 32-bit targets
This enhances location description generation so that the generated
opcodes for integer literals are as space-efficient when HOST_WIDE_INT

DWARF: fix scoping for descriptions of local types
In Ada, it is possible to have nested subprograms in the following
configuration:
procedure Parent is
type T;
[...]
procedure Child (Value : T) is
begin
[...]
end Child;
begin
[...]
end Parent;
As we currently generate debugging information for Child first before
Parent, the debug info for T appears in global scope since the DIE for
Parent does not exist yet.
This patch makes sure that when we generate early debug info for a
nested function, we trigger generation for the parent function first.

Fix gcc.dg/tree-ssa/pr59597.c failure for avr
Declare loop index variable j as a 32 bit int instead of assuming ints
are 32 bits. The smaller int size on the avr makes prior passes optimize
away the loop exit check (j <
10000000), as the constant is outside

Always support float128 on ia64 (PR target/77586).
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).

runtime: copy channel code from Go 1.7 runtime
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.
