Update to the GCC 7.5 release.

This brings more than 215 bug fixes over the GCC 7.4 release and closes
this release branch; that is, no more releases or snapshots.

Update to the GCC 7.4 release.

This fixes more than 190 bugs and includes files/patch-libgfortran
which I had also applied upstream.

On the way create a separate USES block earlier in the Makefile and
moving relevant items there. [1]

Update to the GCC 7.3 release.

This fixes 99+ bugs and includes code generation options to mitigate
Spectre Variant 2 (CVE 2017-5715) for the x86 and powerpc targets
(-mindirect-branch=, -mfunction-return=, and -mindirect-branch-register).

files/patch-armv7-support and files/patch-freebsd-unwind.h, which I
had backported are now included, so remove them.

Welcome GCC 7.1, the first release of the GCC 7 series!

In terms of optimizations, GCC now uses a new local register allocator
(LRA) for most targets (now also including PowerPC and SPARC), a new
store merging pass, is able to determine the return value or range of
return values of some calls to the sprintf family of functions as
input for futher passes, features improved code hoisting, new
interprocedural bitwise constant propagation, interprocedural value
range propagation, new loop splitting, improved shrink-wrapping that
separates portions of prologues and epilogues, and many more.

DWARF 5 is supported through the -gdwarf-5, while DWARF 4 remains the
default for the time being.

The C and C++ frontends have gained a large number of additional
