We must save and restore r19 in both PIC and non-PIC
situations since the kernel paths that clobber r19
are independent of that PIC-ness of userspace.
In addition we choose r4 as the temporary register over
r3 which is being used by recent gcc's as the frame
pointer.

We can discover our x,y coordinate in the core mesh with an
mfspr instruction, multiply y by the core mesh width, and have
the core number without needing to ask the kernel.
Updates the hppa-specific pthread.h from the generic version.
After this update the only difference between the generic
version and the hppa version is the footer protected by the
_PTHREAD_H_HPPA_ guard.
The new strtod function wants rounding information from the C lib, so
move the guts of the ia64 version into a header file for it to use.

The ia64 gcc port has never shipped a crtbeginT.o, so keep using the
old crtbegin.o object when static linking.

Fix a build failure by using __prlimit64 as the internal
function name for the versioned symbol prlimit64. Without
this patch the build system attempts to alias prlimit64
to itself and that is invalid.
The convert_bit macro allows the compiler to translate the bit
positions more efficiently. The assumption of only running at
program startup allows eliding the __ieee_get_fp_control call.
The previous dummy definition (as type int) was fine in general, since
tile doesn't have floating-point registers, but it confused gdb's
configure, leading to later compile errors. This change also makes
prfpregset_t parallel to prgregset_t, which seems like generally the
right thing regardless of the non-existence of the actual registers :-)
We've been carrying this in Gentoo for quite a long time to fix some test
failures that people hit.

This test fails since the read back fpu control word is 0x80000 instead
of 0x0. I wonder if this patch is correct:
...
which additionally masks out the condition bit 23 - note that the other
condition bits (25-31) are masked out too?
