compiler: Accept untyped integral values as string/array indices.

    When determining the type of an index for a string/array indexing
    expression, the gofrontend would disallow floating-point and complex
    values even if they were integral and throw an internal error.  This
    patch changes gofrontend to use an integral type context when
    determining the types of a string/array index.

    Fixes golang/go#11545.

remove dead code of commutative_reductions

based on the ISL scheduler.)  We will add back the detection of commutative
reductions after we improve the code generation of scalar dependences (by not
going out of SSA for scalar dependences just to expose them to the data

Update soft-fp from glibc.

This patch updates the soft-fp code in libgcc from glibc.  There are
no changes here of significance to the use of soft-fp in GCC (and so
no testsuite additions); it's simply an update to bring in the latest
soft-fp version (which will also hopefully go into Linux 4.4 to
replace the 15-year-old copy currently in Linux).

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Redesign Graphite scop detection

Redesign Graphite scop detection for faster compiler time and detecting more SCoPs.

Existing algorithm for SCoP detection in graphite was based on dominator tree
where a tree (CFG) traversal was required for analyzing an SESE. The tree
traversal is linear in the number of basic blocks and SCoP detection is
(probably) linear in number of instructions. That algorithm utilized a generic
infrastructure of SESE which does not directly represent loops.  With regards to
graphite framework, we are only interested in subtrees with loops. The new
algorithm is geared towards tree traversal on loop structure. The algorithm is
linear in number of loops which is faster than the previous algorithm.

Briefly, we start the traversal at a loop-nest and analyze it recursively for
validity. Once a valid loop is found we find a valid adjacent loop. If an
adjacent loop is found and is valid, we merge both loop nests otherwise we form
a SCoP from the previous loop nest, and resume the algorithm from the adjacent
loop nest. The data structure to represent an SESE is an ordered pair of edges
(entry, exit). The new algoritm can extend a SCoP in both the directions. With
this approach, the number of instructions to be analyzed for validity reduces to
a minimal set.  We start by analyzing those statements which are inside a loop,
because validity of those statements is necessary for the validity of loop. The
statements outside the loop nest can be just excluded from the SESE if they are
not valid.

This patch depends on: https://gcc.gnu.org/ml/gcc-patches/2015-09/msg02024.html

Passes (c,c++,fortran) regtest and bootstrap.

revert to assign_parms assignments using default defs

Revert the fragile and complicated changes to assign_parms designed to
enable it to use RTL assigments chosen by cfgexpand, and instead have
cfgexpand use the RTL assignments by assign_parms, keying them off of
the default defs that are now necessarily introduced for each parm and
result.  The possible lack of a default def was already a problem, and
the fallbacks in place were not enough, as shown by PR67312.  We now
have checking asserts in set_rtl that verify that we're assigning to
each var a piece of RTL that matches the expectations set forth by
use_register_for_decl.

PR pretty-print/67567 do not pass NULL as a string

Fortran passes NULL where a non-null string is expected by the pretty-printer,
which causes a sanitizer warning. This could have been found earlier by using
gcc_checking_assert. Even if the assertion is false, the result is just an
incomplete diagnostic, thus it seems more user-friendly to assert only when
checking. I do not have any idea how to properly fix the Fortran bug, thus this

[AArch64] Force __builtin_aarch64_fp[sc]r argument into a REG

The testcase triggered an ICE because the builtin expansion
code passed the output of expand_normal directly to the SET_FP[SC]R
generator, without forcing it into a register first.
