Split class rtx_reader into md_reader vs rtx_reader
This moves read_rtx and friends into rtx_reader, and splits
rtx_reader into two classes:
class md_reader: has responsibility for reading chars, managing
include files, top-level directives etc. It is the read-md.o part.
class rtx_reader, a subclass, has the code for reading hierarchical
rtx expressions using the format codes. It is the read-rtl.o part.
This split is needed by a followup patch, which converts
read_rtx_operand to a virtual function of rtx_reader. To do this,
instances of rtx_reader (or its subclasses) need a vtable, which
needs to include a ptr to the code in read-rtl.o. Splitting it up
allows the gen* tools that currently purely use read-md.o to continue
to do so.

GCC caches the whether a function is a leaf in crtl->is_leaf.
GCC caches the whether a function is a leaf in crtl->is_leaf. Using this
in the backend is best as leaf_function_p may not work correctly (eg. while
emitting prolog or epilog code). There are many reads of crtl->is_leaf
before it is initialized. Many targets do in targetm.frame_pointer_required
(eg. arm, aarch64, i386, mips, sparc), which is called before register
allocation by ira_setup_eliminable_regset and sched_init.
Additionally, SHRINK_WRAPPING_ENABLED calls targetm.have_simple_return,
which evaluates the condition of the simple_return instruction. On ARM
this results in a call to use_simple_return_p which requires crtl->is_leaf
to be set correctly.
To fix this, initialize crtl->is_leaf in ira_setup_eliminable_regset and
early on in ira. A bootstrap did not find any uninitialized reads of
crtl->is_leaf on Thumb-2. A follow-up patch will remove incorrect uses
of leaf_function_p from the ARM backend.
