The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer. The signness doesn't matter here, so
convert it to unsigned.

The strcpy and strchr (and related) functions are four times faster
than the byte-by-byte default versions.
The strlen function is twice as fast for long strings and 50% faster
for short strings over the armv4 version.

Written from scratch rather than copied from GMP, due to LGPL 2.1 vs
GPL 3, but tested with the GMP testsuite.
This is 250% faster than the generic code as measured on Cortex-A15,
and the same speed as GMP on the same core, and probably everywhere.

It is 25% slower than the current GMP routine on the same core.

There was only one user. It's "condition" argument was used
for "ia" rather than an actual condition. The apcs26 syntax
is almost certainly not needed, given current binutils requirements.
For arm this makes no difference--the result is bit-for-bit identical;
for thumb this results in smaller encodings. Perhaps it ought not and
this is in fact an assembler bug, but I also think it's clearer.
The preceeding patches have allowed for the few incompatibilities
between arm and thumb2 mode, or have marked the file as not wanting
to use thumb2 mode.
Factor out the sequence needed to call kuser_get_tls, as we can't
play subtract into pc games in thumb mode. Prepare for hard-tp,
pulling the save of LR into the macro.
There are several places in which we access negative offsets from
the thread-pointer, but thumb2 only supports positive offsets in
memory references.
Avoid duplicating the rather large macros in which these references
are embedded by abstracting out the operation.
Some routines are written with complex LDM/STM insns that cannot be
used in thumb mode, or are highly conditional requiring excessive
IT insns.
When a future patch goes in to enable thumb2 by default, this marker
will be used to override that default.
New defines from gcc 4.8:
#define __ARM_ARCH_ISA_ARM 1
#define __ARM_ARCH_PROFILE 65
#define __ARM_ARCH_ISA_THUMB 2
#define __ARM_ARCH 7
all of which got in the way of the one we wanted:
#define __ARM_ARCH_7A__ 1
