Most changes are mechanical replacement of 'retw' instruction with
'abi_ret' macro, defined to 'retw' or 'ret' according to ABI.
Assembly code that makes calls is duplicated for call0 ABI with changed
register numbers for parameters/return value and call instruction.
'entry' instructions are replaced with 'abi_entry' macro.
More interesting changes:
- non-leaf assembly functions (e.g. _dl_tlsdesc_dynamic,
_dl_linux_resolve, SYSCALL_ERROR_HANDLER, PSEUDO) now need to preserve
registers around intermediate calls they make, use temporary stack
frame for that;
- setjmp/longjmp only need to save and restore return address, stack
pointer and callee-saved registers in the jmpbuf;
- __clone and syscall functions had hardcoded offsets to parameter
passed on stack, on call0 ABI they don't need stack frame, so the
offset is different. Replace these offsets with FRAMESIZE macro.

TLS_LD should use linker-provided symbol _TLS_MODULE_BASE_ instead of
symbol it resolves to get thread pointer, otherwise linker relaxation
doesn't work correctly, adding extra offset to thread-local variable
address.
This fixes most of tls/tst-tls* tests.

Based on Peter Mazinger's comments on a recent commit, I decided
to get rids of all occurrences of PIC changing them to __PIC__

* Add a GLIBC_TESTS_DISABLED var because many of these tests
need internal uClibc stuff. This disables the HOSTCC build of
these tests
* Fix up tls test macros for x86
* Fix the linking of the tls tests
