The full general-instruction-extension facility was added to binutils
after the change to GPLv3.  This is not the entire extension, just
what we're using in TCG.

Making an xyzdir variable for each directory prepares for the next
patches introducing config-host.h defines and configure options for them.
It also fixes the problem where overriding prefix at "make install"
time did not override it for sysconfdir.

Removes some of the differences between sysconfdir and other variables,
the rest will go away later.

Change code handling mips16-specific branches to use ISA-neutral special
opcodes.  Since there are several places where the delay slot
requirements for microMIPS branches differ from mips16 branches, using
opcodes is easier than checking hflags, then checking mips16
vs. microMIPS.

Commit dd4239d6 broke multiboot. It replaced the
instruction "rep insb (%dx), %es:(%edi)" by the binary output of
"addr32 rep insb (%dx), %es:(%di)".

Linuxboot calls the respective helper function in a code16 section. So the
original instruction was automatically translated to its "addr32" equivalent.
For multiboot, we're running in code32 so gcc didn't add the "addr32" which
breaks the instruction.

This patch splits that helper function in one which uses addr32 and one which
does not, so everyone's happy.

The good news is that nobody probably cared so far. The bundled multiboot.bin
binary was built before the change and is thus correct.

Please also put this patch into -stable.

Mirror tcg_out_movi in having a TYPE parameter.  This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.

Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"
as represented by the existing TCG_TYPE_PTR.

Update all targets to match.
