A recently-added test (dlfcn/tststatic5) pointed out that tile was not
properly initializing the variable pagesize in certain cases. This
change just copies the existing code from MIPS.
This function is now called from dl_open_worker with the GL(dl_load_lock)
lock held and no longer needs local protection. GL(dl_load_lock) also
correctly protects _dl_lookup_symbol_x called here that relies on the
caller to have serialized access to the data structures it uses.
This patch introduces two new convenience functions to set the default
thread attributes used for creating threads. This allows a programmer
to set the default thread attributes just once in a process and then
run pthread_create without additional attributes.
The macros in lowlevellock.h are returning positive errors, but the
users of the macros expect negative. This causes e.g. sem_wait to
sometimes return an error with errno set to -EWOULDBLOCK.

These macros often set up a variable that later macros sometimes do
not use. Add unused attribute to avoid that.
Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning. Replace this with a dummy reference.

Function pointers on ia64 are like parisc -- they're plabels. While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.
Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.

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.

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.
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.
