0f876f2288 PR28901 -Wunused-variable ignores unused const initialised variables in C 
12 years ago it was decided that -Wunused-variable shouldn't warn about
static const variables because some code used const static char rcsid[]
strings which were never used but wanted in the code anyway. But as the
bug points out this hides some real bugs. These days the usage of rcsids
is not very popular anymore. So this patch changes the default to warn
about unused static const variables in C with -Wunused-variable. And it
adds a new option -Wno-unused-const-variable to turn this warning off.
For C++ this new warning is off by default, since const variables can be
used as #defines in C++. New testcases for the new defaults in C and C++
are included testing the new warning and suppressing it with an unused
attribute or using -Wno-unused-const-variable.

2f0c2a0cc4 remove STRUCT_VALUE macro 
This macro was converted to the TARGET_STRUCT_VALUE_RTX hook many years
ago, however there are still some lingering definitions, and a use in
libobjc.  All the remaining definitions define the macro to 0, which
libobjc treats the same as undefined, so it won't break anything else to
have libobjc stop checking the macro.  However it may be that this part
of libobjc has been broken for a long time on targets that only define
the hook, but that is a separate issue.

09fcd8e149 Remove separate movtf pattern - Use an iterator for all FP modes. 
movtf is unnecessary as a separate expander. Move this to be with
the standard scalar floating point expanders.

Achieved by adding a new iterator and then using the same.

Tested cross aarch64-none-elf and no regressions.
