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. 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.

    gcc/
	* gcc/ira.c (ira_setup_eliminable_regset): Initialize crtl->is_leaf.
	(ira): Move initialization of crtl->is_leaf earlier.

Improve TI mode address offsets - these may either use LDP of 64-bit or
LDR of 128-bit, so we need to use the correct intersection of offsets.
When splitting a large offset into base and offset, use a signed 9-bit 
unscaled offset.

Remove the Ump constraint on movti and movtf instructions as this blocks
the reload optimizer from merging address CSEs (is this supposed to work
only on 'm' constraints?).  The result is improved codesize, especially
wrf and gamess in SPEC2006.
