[rfa v2] Detect __aeabi_read_tp even without symbols

[Ulrich Weigand]

> 	* arm-tdep.c (skip_prologue_function): Add GDBARCH and IS_THUMB
> 	arguments.  Skip in-prologue calls to glibc __aeabi_read_tp
> 	implementation even if no symbols are available.
> 	(thumb_analyze_prologue): Update call to skip_prologue_function.
> 	(arm_analyze_prologue): Likewise.

I've checked this in as well.

Bye,
Ulrich
