I've noticed
make: Circular build/genrvv-type-indexer.o <- gtype-desc.h dependency dropped.

The following patch fixes that.  The RTL_BASE_H variable includes a lot of
headers which the generator doesn't include, including gtype-desc.h.
I've preprocessed it and checked all gcc/libiberty headers against what is
included in the other dependency variables and here is what I found:
1) coretypes.h includes align.h, poly-int.h and poly-int-types.h which
   weren't listed (most of dependencies are thankfully done automatically,
   so it isn't that big deal except for these generators and the like)
2) system.h includes filenames.h (already listed) but filenames.h includes
   hashtab.h; instead of adding FILENAMES_H I've just added the dependency
   to SYSTEM_H
3) $(RTL_BASE_H) wasn't really needed at all and insn-modes.h is already
   included in $(CORETYPES_H)

Backport CL 421442 from upstream.

Original description:

Arrange for tests that call setMimeInit to fully restore the old values,
by clearing the sync.Once that controls initialization.

Once we've done that, call initMime in initMimeUnixTest because
otherwise the test types loaded there will be cleared by the call to
initMime that previously was not being done.

	* gcc.target/powerpc/ppc-fortran/ppc-fortran.exp: Test for
	fortran compiler, skip if missing.

This is just a minor issue I found with a previous test
of mine that caused it to fail in C++ mode due to these
unused const variables being uninitialised. I forgot to
remove these after removing some test cases that did use
them. I removed the test cases, because I came to the
conclusion that the const-ness of the immediate was
irrelevant to the test itself.
Removing the variables now makes the test PASS for C++.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/mve/intrinsics/mve_intrinsic_type_overloads-fp.c: Remove unused variables.
	* gcc.target/arm/mve/intrinsics/mve_intrinsic_type_overloads-int.c: Remove unused variables.

My change r13-416-g485a0ae0982abe caused the compiler to stop
generating auto-inc operations on mve loads and stores.  The fix
is to check whether there is a replacement register available
when in strict mode and the register is still a pseudo.

'dg-excess-errors' "indicates that the test is expected to fail due to compiler
messages that are not handled by 'dg-error', [etc.]".  It's argument doesn't
specify the message to match but just just a comment.  Here, however, we'd like
to match specific compiler messages, so we should use 'dg-error', etc.  Use the
magic line number zero as the compiler error diagnostic doesn't tell which line
the error occurred on (separate issue to resolve).  This gives us:
