This long patch only does one simple thing, adds an explicit function
parameter to predicates stmt_could_throw_p, stmt_can_throw_external
and stmt_can_throw_internal.

My motivation was ability to use stmt_can_throw_external in IPA
analysis phase without the need to push cfun.  As I have discovered,
we were already doing that in cgraph.c, which this patch avoids as
well.  In the process, I had to add a struct function parameter to
stmt_could_throw_p and decided to also change the interface of
stmt_can_throw_internal just for the sake of some minimal consistency.

In the process I have discovered that calling method
cgraph_node::create_version_clone_with_body (used by ipa-split,
ipa-sra, OMP simd and multiple_target) leads to calls of
stmt_can_throw_external with NULL cfun.  I have worked around this by
making stmt_can_throw_external and stmt_could_throw_p gracefully
accept NULL and just be pessimistic in that case.  The problem with
fixing this in a better way is that struct function for the clone is
created after cloning edges where we attempt to push the yet not
existing cfun, and moving it before would require a bit of surgery in
tree-inline.c.  A slightly hackish but simpler fix might be to
explicitely pass the "old" function to symbol_table::create_edge
because it should be just as good at that moment.  In any event, that
is a topic for another patch.

I believe that currently we incorrectly use cfun in
maybe_clean_eh_stmt_fn and maybe_duplicate_eh_stmt_fn, both in
tree-eh.c, and so I have fixed these cases too.  The bulk of other
changes is just mechanical adding of cfun to all users.

Bootstrapped and tested on x86_64-linux (also with extra NULLing and
restoring cfun to double check it is not used in a place I missed), OK
for trunk?

Thanks,

Martin

Improves the code generation by getting rid of redundant LAs, as seen
in the following example:

	-	la	%r1,0(%r13)
	-	lg	%r4,0(%r1)
	+	lg	%r4,0(%r13)

Also allows to proceed with the merge of movdi_64 and movdi_larl.
Currently LRA decides to spill literal pool references back to the
literal pool, because it preliminarily chooses alternatives with
CT_MEMORY constraints without calling
satisfies_memory_constraint_p (). Later on it notices that the
constraint is wrong and fixes it by spilling.  The constraint in this
case is "b", and the operand is a literal pool reference.  There is
no reason to reject them.  The current behavior was introduced,
apparently unintentionally, by
https://gcc.gnu.org/ml/gcc-patches/2010-09/msg00812.html

The patch affects a little bit more than mentioned in the subject,
because it changes s390_loadrelative_operand_p (), which is called not
only for checking the "b" constraint.  However, the only caller for
which it should really not accept literal pool references is
s390_check_qrst_address (), so it was changed to explicitly do so.

Many AVX512 vector operations can broadcast from a scalar memory source.
This patch enables memory broadcast for FMSUB operations.  In order to
support AVX512 memory broadcast for FMSUB, FMSUB builtin functions are
also added, instead of passing the negated value to FMA builtin functions.

As a GNU extension we allow containers to be instantiated with
allocators that use a different value type from the container, and
automatically rebind the allocator to the correct type. This extension
is disabled in strict modes (when __STRICT_ANSI__ is defined, i.e.
-std=c++NN dialects). These testcases unintentionally rely on the
extension and so fail for strict modes.

Tests which intentionally make use of the extension will still fail in
strict dialects, but will be addressed in a later change.

    This keeps init functions from appearing in the export data.  Checking
    for special names in general means that we don't need to check
    specifically for nested functions or thunks, which have special names.

	PR tree-optimization/87473
	* gimple-ssa-strength-reduction.c (record_phi_increments_1): For
	phi arguments identical to the base expression of the phi
	candidate, record a phi-adjust increment of zero minus the index
	expression of the hidden basis.
	(phi_incr_cost_1): For phi arguments identical to the base
	expression of the phi candidate, the difference to compare against
	the increment is zero minus the index expression of the hidden
	basis, and there is no potential savings from replacing the (phi)
	statement.
	(ncd_with_phi): For phi arguments identical to the base expression
	of the phi candidate, the difference to compare against the
	increment is zero minus the index expression of the hidden basis.
	(all_phi_incrs_profitable_1): For phi arguments identical to the
	base expression of the phi candidate, the increment to be checked
	for profitability is zero minus the index expression of the hidden
	basis.

IRA and LRA prefer to use CR7 (which is first in REG_ALLOC_ORDER) over
CR0, although the latter often is cheaper ("x" vs. "y" constraints).
We should figure out why this is and fix it; but until that is done,
this patch makes CR0 the first allocated register: it improves the
current code, and it is required for later patches to be effective.

(It changes two testcases to no longer look at what CR field is
allocated).


	* config/rs6000/rs6000.h (REG_ALLOC_ORDER): Move 68 (that is, CR0) to
	be the first CR field allocated.

gcc/testsuite/
	* gcc.target/powerpc/safe-indirect-jump-2.c: Do not check assigned CR
	field number.
	* gcc.target/powerpc/safe-indirect-jump-3.c: Ditto.

This fixes the following testsuite failures on ia32 when compiled with
-D_GLIBCXX_DEBUG:

The normal mode containers already use the abi-tag to mangle these
overloads differently, but the debug mode versions weren't fixed.

	* include/debug/map.h (map::erase(iterator)): Add abi-tag so that
	C++11 version mangles differently from incompatible C++98 version.
	* include/debug/multimap.h (multimap::erase(iterator)): Likewise.
