Add a new option --clean_build to validate_failures.py

This is useful when you have two builds of the same compiler.  One with
your changes.  The other one, a clean build at the same revision.
Instead of using a manifest file, --clean_build will compare the
results it gather from the patched build against those it gathers from
the clean build.

Usage

$ cd /top/of/patched/gcc/bld

This patch removes the unused ebitmap, and then removes some sbitmap functions
only used by ebitmap.  The functions removed are:

SET_BIT_WITH_POPCOUNT
RESET_BIT_WITH_POPCOUNT
bitmap_copy_n
bitmap_range_empty_p
sbitmap_popcount

In addition, two functions have been made private to the implementation file:

SBITMAP_SIZE_BYTES
sbitmap_verify_popcount

Tested on x86-64.

This patch renames sbitmap iterators to unify them with the bitmap iterators.

Remove the unused EXECUTE_IF_SET_IN_SBITMAP_REV, which has an unconventional
interface.

Rename the sbitmap_iter_* functions to match bitmap's bmp_iter_* functions.
Add an additional parameter to the initialization and next functions to
match the interface in bmp_iter_*.  This extra parameter is mostly hidden
by the use of the EXECUTE_IF macros.

Rename the EXECUTE_IF_SET_IN_SBITMAP macro to EXECUTE_IF_SET_IN_BITMAP.  Its
implementation is now identical to that in bitmap.h.  To prevent redefinition
errors, both definitions are now guarded by #ifndef.  An alternate strategy
is to simply include bitmap.h from sbitmap.h.  As this would increase build
time, I have elected to use the #ifndef version.  I do not have a strong
preference here.

The sbitmap_iterator type is still distinctly named because it is often
declared in contexts where the bitmap type is not obvious.  There are less
than 40 uses of this type, so the burden to modify it when changing bitmap
types is not large.

Tested on x86-64, config-list.mk testing.

This patch implements generic type query and conversion functions,
and applies them to the use of cgraph_node, varpool_node, and symtab_node.

The functions are:

bool is_a <TYPE> (pointer)
  Tests whether the pointer actually points to a more derived TYPE.

TYPE *as_a <TYPE> (pointer)
  Converts pointer to a TYPE*.

TYPE *dyn_cast <TYPE> (pointer)
  Converts pointer to TYPE* if and only if "is_a <TYPE> pointer".
  Otherwise, returns NULL.
  This function is essentially a checked down cast.

These functions reduce compile time and increase type safety when treating a
generic item as a more specific item.  In essence, the code change is from

  if (symtab_function_p (node))
    {
      struct cgraph_node *cnode = cgraph (node);
      ....
    }

to

  if (cgraph_node *cnode = dyn_cast <cgraph_node> (node))
    {
      ....
    }

The necessary conditional test defines a variable that holds a known good
pointer to the specific item and avoids subsequent conversion calls and
the assertion checks that may come with them.

When, the property test is embedded within a larger condition, the variable
declaration gets pulled out of the condition.  (This leaves some room for
using the variable inappropriately.)

  if (symtab_variable_p (node)
      && varpool (node)->finalized)
    varpool_analyze_node (varpool (node));

becomes

  varpool_node *vnode = dyn_cast <varpool_node> (node);
  if (vnode && vnode->finalized)
    varpool_analyze_node (vnode);

Note that we have converted two sets of assertions in the calls to varpool
into safe and efficient use of a variable.

There are remaining calls to symtab_function_p and symtab_variable_p that
do not involve a pointer to a more specific type.  These have been converted
to calls to a functions is_a <cgraph_node> and is_a <varpool_node>.  The
original predicate functions have been removed.

The cgraph.h header defined both a struct and a function with the name
varpool_node.  This name overloading can cause some unintuitive error messages
when, as is common in C++, one omits the struct keyword when using the type.
I have renamed the function to varpool_node_for_decl.

Tested on x86_64.
