[BZ #19129][ARM] Fix _dl_tlsdesc_resolve_hold to save r0
_dl_tlsdesc_resolve_hold calls into a C function that clobbers r0, but it assumes the original argument is still in r0 after the call. This can cause crash in case of concurrent TLS access when TLSDESC is in use (-mtls-dialect=gnu2). Run into this while fixing BZ 18572. Both r0 and r1 are saved/restored so the stack remains 8 byte aligned. [BZ #19129] * sysdeps/arm/dl-tlsdesc.S (_dl_tlsdesc_resolve_hold): Save and restore r0 and r1.
