PR10491 Don't assign to REG_IP if it isn't an lvalue (s390 and ia64).
To fixup REG_IP to show the correct value after a [ku]probe trap we
assigned the address of the actual instruction pointer of the probed
instruction. That doesn't work on architectures, s390 and ia64, where
REG_IP is not a simple lvalue. Just don't try to fixup the address in
those cases. If this isn't enough, the uprobe_stmt_num.exp testcase
will point this out.
* runtime/regs.h: Define REG_IP_LVALUE for x86_64, i386, powerpc64 and arm.
* tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Only fixup
REG_IP when REG_IP_LVALUE is defined.
(uprobe_derived_probe_group::emit_module_decls): Likewise.
(kprobe_derived_probe_group::emit_module_decls): Likewise.
