This patch fixes PR 58944
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58944

ix86_valid_target_attribute_tree in config/i386/i386.c was
refactored to not depend on global_options structure and to be able to
use any gcc_options structure.  One clean way to fix this is by having
target_option_default_node save all the default target options which
can be restored to any gcc_options structure. The root cause of the
above bugs was that ix86_arch_string and ix86_tune_string was not
saved in target_option_deault_node.

This patch saves all the  target options used in i386.opt which are
either obtained from the command-line or set to some default.

Testing:
Patch tested for bootstrap on all default languages(also obj-c++ and ada)
on x86_64 and regression testsuite checked for parity with RUNTESTFLAGS -m32

libgo: Avoid some cases of getting callers recursively.

Avoids hanging inside older versions of glibc that do not
support recurive calls to dl_iterate_phdr.

reflect: Rename struct field to be consistent in assembler and Go.

reflect: Fix MakeFunc for 386 when returning a struct.

When a 386 function returns a struct, it needs to return using

the stack.  That wasn't happening.

* combine.c (reg_nonzero_bits_for_combine): Apply mask transformation
as applied to nonzero_sign_valid when last_set_mode has less precision
than mode.
