rs6000: Fix split of ashdi3_extswsli_dot for memory (PR71670)

The splitter for ashdi3_extswsli_dot for cr0 with memory uses emit_insn
gen_ashdi3_extswsli_dot, which does not work because that emits a scratch,
while the splitter runs after reload so there should be a real register
instead.  We can laboriously fix that up, or emit using
gen_ashdi3_extswsli_dot2 instead.  This patch does the latter.

Add make autoprofiledbootstrap

Add support for profiledbootstrap with autofdo. Will be useful
to get better testing coverage of autofdo.

This requires Linux perf and autofdo to be installed, only
really for x86_64 linux on Intel so far.

Profile the whole build process with perf, then convert the file,
and pass it back to the compiler in the feedback stage.

The conversion has to be done per language, as only that knows
the name of the binary. Currently we only do it for C and C++,
as the other languages don't have enough coverage during a normal
bootstrap.

For lto1 it is also disabled, because it would only be useful during a LTO
bootstrap, but right now autofdo and LTO are not working together due to
PR66229

For common backend files always the profile output of the C++ compiler
is used. In theory multiple inputs could be merged here, but so far
that is not implemented.

The method is not friendly to partial rebuilds, as only the profile
information from the current rebuild is used. So if an error
occurs it is best to clean and restart, otherwise the code
quality may be worse.

This patch is fairly large, but most of it is auto generated from
autogen in Makefile.in. for the new stage targets.

Passes profiledbootstrap and normal bootstrap on x86_64-linux.
autoprofiledbootstrap is currently not working due to
PR70427 (but it finishes with that worked around)

The autofdo'ed compiler is ~7% faster on insn-recog.i (vs ~11% for
profiledfeedback), and ~4% faster for tramp3d-v4 (vs 10% for
profiledfeedback) on a Sandy Bridge system.

Run profile feedback tests with autofdo

Extend the existing bprob and tree-prof tests to also run with autofdo.
The test runtimes are really a bit too short for autofdo, but it's
a reasonable sanity check.

This only works natively for now.

dejagnu doesn't seem to support a wrapper for unix tests, so I had
to open code running these tests.  That should be ok due to the

Add gcc-auto-profile script

Using autofdo is currently something difficult. It requires using the
model specific branches taken event, which differs on different CPUs.
The example shown in the manual requires a special patched version of
perf that is non standard, and also will likely not work everywhere.

This patch adds a new gcc-auto-profile script that figures out the
correct event and runs perf.

This is needed to actually make use of autofdo in a generic way
in the build system and in the test suite.

Since maintaining the script would be somewhat tedious (needs changes
every time a new CPU comes out) I auto generated it from the online
Intel event database. The script to do that is in contrib and can be
rerun.

Right now there is no test if perf works in configure. This
would vary depending on the build and target system, and since
it currently doesn't work in virtualization and needs uptodate
kernel it may often fail in common distribution build setups.

So far the script is not installed.

2016-06-22  Ed Schonberg  <schonberg@adacore.com>

* sem_prag.ads (Build_Classwide_Expression): new procedure to
build the expression for an inherited classwide condition, and
to validate such expressions when they apply to an inherited
operation that is not overridden.
* sem_prag.adb (Primitives_Mapping): new data structure to
handle the mapping between operations of a root type and the
corresponding overriding operations of a type extension. Used
to construct the expression for an inherited classwide condition.
(Update_Primitives_Mapping): add to Primitives_Mapping the links
between primitive operations of a root type and those of a given
type extension.
(Build_Pragma_Check_Equivalent): use Primitives_Mapping.
* sem_ch6.adb (New_Overloaded_Entity): Remove call to
Collect_Iherited_Class_Wide_Conditions in GNATprove_Mode. This
needs to be done at freeze point of the type.
* freeze.adb (Check_Inherited_Conditions): new procedure to
verify the legality of inherited classwide conditions. In normal
compilation mode the procedure determines whether an inherited
operation needs a wrapper to handle an inherited condition that
differs from the condition of the root type.  In SPARK mode
the routine invokes Collect_Inherited_Class_Wide_Conditions to
produce the SPARK version of these inherited conditions.
(Freeze_Record_Type): For a type extension, call
Check_Inherited_Conditions.
