runtime: copy memory hash code from Go 1.7

    Rewrite the AES hashing code from gc assembler to C code using
    intrinsics.  The resulting code generates the same hash code for the
    same input as the gc code--that doesn't matter as such, but testing it
    ensures that the C code does something useful.

runtime: allocate _panic struct on heap

    The gc library allocates a _panic struct on the stack. This does not
    work for gccgo, because when a deferred function recovers the panic we
    unwind the stack up to that point so that returning from the function
    will work correctly.

    Allocating on the stack fine if the panic is not recovered, and it
    works fine if the panic is recovered by a function that
    returns. However, it fails if the panic is recovered by a function
    that itself panics, and if that second panic is then recovered by a
    function higher up on the stack. When we unwind the stack to that
    second panic, the g will wind up pointing at a panic farther down on
    the stack. Even then everything will often work fine, except when the
    deferred function catching the second panic makes a bunch of calls
    that use stack space before returning. In that case the code can
    overwrite the panic struct, which will then cause disaster when we
    remove the struct from the linked list, as the link field will be
    garbage. This case is rare enough that all the x86 tests were passing,
    but there was a failure on ppc64le.

    Before https://golang.org/cl/33414 we allocated the panic struct on
    the heap, so go back to doing that again.

    Fixes golang/go#18228.

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.

* gcc/ira.c (ira_setup_eliminable_regset): Initialize crtl->is_leaf.
