Treat .eh_frame section before crtbeginT as normal input
Force the exception frame section from input files before the crtbeginT
file to be handled as an ordinary input section if we aren't creating
the exception frame header. If we don't do this, we won't correctly
handle the special marker symbol in the exception frame section in the
crtbeginT file.

* ehframe.h (Eh_frame::add_ehframe_input_section): Add a
bool parameter to indicate if the exception frame section
can be optimized.
* layout.cc (Layout::Layout): Initialize optimize_ehframe_ to
!has_crtbeginT.

if there is a crtbeginT file and the last one is a crti file.
* options.h (Input_arguments::Input_arguments): Initialize
has_crtbeginT_ and last_is_crti_ to false.
(Input_arguments::has_crtbeginT): New function.
