bb-reorder: Add -freorder-blocks-algorithm= and wire it up

This adds an -freorder-blocks-algorithm=[simple|stc] flag, with "simple"
as default.  For -O2 and up (except -Os) it is switched to "stc" instead.
Targets that never want STC can override this.  This changes -freorder-blocks
to be on at -O1 and up (was -O2 and up).

In effect, the changes are for -O1 (which now gets "simple" instead of
nothing), -Os (which now gets "simple" instead of "stc", since STC results
in much bigger code), and for targets that wish to never use STC (not in

[RS6000] Correct powerpc sysv stack argument accounting

ppc32 starts using the stack for integer arg passing when we run out
of integer arg passing registers.  Similarly, we start using the stack
for floating point args when we run out of floating point registers.
The decision on where an integer arg goes does not depend on number of
floating point args, nor does the decision on where a floating point
arg goes depend on number of integer args.  Alignment of stack args
also simply depends on number of stack args.

wrongly used to count both integer args and stack words.

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.

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).

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.

re PR tree-optimization/67700 ([graphite] miscompile due to wrong codegen)

fix PR67700

The patch makes the detection of scop parameters in parameter_index_in_region a
bit more conservative by discarding scalar variables defined in function of data
references defined in the scop.

Make muser-mode the default for LEON3

The muser-mode flag causes the CASA instruction for LEON3 to use the
user mode ASI. This is the correct behavior for almost all LEON3 targets.
