Preserve the original program while using graphite.

Earlier, graphite used to translate portions of the original program after
scop-detection in order to represent the SCoP into polyhedral model.  This was
required because each basic block was represented as independent basic block in
the polyhedral model. So all the cross-basic-block dependencies were translated
out-of-ssa.

With this patch those dependencies are also exposed to the ISL, so there is no
need to modify the original structure of the program.

After this patch we should be able to enable graphite at some default
optimization level.

Highlights:
Remove cross bb scalar to array translation
For reductions, add support for more than just INT_CST
Early bailout on codegen.
Verify loop-closed ssa structure during copy of renames
The uses of exprs should come from bb which dominates the bb
Collect the init value of close phi in loop-guard
Do not follow vuses for close-phi, postpone loop-close phi until the
    corresponding loop-phi is processed
Bail out if no bb found to place cond/loop -phis
Move insertion of liveouts at the end of codegen
Insert loop-phis in the loop-header.

This patch passes regtest and bootstrap with BOOT_CFLAGS='-O2 -fgraphite-identity -floop-nest-optimize'

improve construction of the original schedule

The patch builds the original schedule based on the now optimized scattering
dimension instead of building one based on the loop index only.

The implementation is simpler and catches more cases where the original schedule
and the transformed schedule are the same, such as the one below:

for (i = 0; i < 1000; i++)
{
  Temp = F[i];
  for (j = 0; j < 1000; j++)
 {
    D[j] = E[j]  * Temp;
    A[i][j] = A[i][j]  + B[i][j] * C[i][j] - D[j] ;
  }
  D[i] = E[i] * F[i];
}

  isl_union_map_add_map on every pbb->schedule.

    This is, in effect, what the gc toolchain does.  It fixes cases where Go
    code refers to a C global variable; without this, if the global variable
    was the only thing visible in the C code, the generated cgo file might
    not get pulled in from the archive, leaving the Go variable
    uninitialized.

    This was reported against gccgo as https://gcc.gnu.org/PR68255 .
