Move #undef DEF_BUILTIN* to builtins.def

I was confused at first why tree-core.h was undefining DEF_BUILTIN_CHKP
before defining it, then undefining it again after including builtins.def.
This is because builtins.def provides a default definition of
DEF_BUILTIN_CHKP, but leaves it up to the caller to undefine it where
necessary.  Similarly to the previous internal-fn.def patch, it seems
more obvious for builtins.def to #undef things unconditionally.

One argument might have been that keeping preprocessor stuff
out of the .def files makes it easier for non-cpp parsers.  In practice
though we already have #ifs and multiline #defines, so single-line #undefs
should be easy in comparison.

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Move #undef DEF_INTERNAL_FN to internal-fn.def

In practice the definition of DEF_INTERNAL_FN is never reused after
including internal-fn.def, so we might as well #undef it there.

This becomes more obvious with a later patch that adds other
DEF_INTERNAL_* directives, such as DEF_INTERNAL_OPTAB_FN.
If the includer doesn't care about the information carried in
these new directives, it can simply leave the macro undefined
and internals.def will provide a definition that forwards to
DEF_INTERNAL_FN.  It doesn't make much sense for includers to have
to #undef macros that are defined by internals.def and it seems overly
complicated to get internals.def to undef macros only in the cases
where it provided a definition.  Instead I went with the approach of
#undeffing all the DEF_INTERNAL_* macros unconditionally.

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Move const char * -> int/fp folds to fold-const-call.c

This patch moves folds that deal with constant string arguments and
return a constant integer or floating-point value.  For example, it
handles strcmp ("foo", "bar") but not strstr ("foobar", "bar"),
which wouldn't currently be accepted by the gimple folders.

The builtins.c folding for strlen (via c_strlen) is a bit more general
than what the fold-const-call.c code does (and more general than we need
for the gimple folders).  I've therefore left it as-is, even though it
partially duplicates the new code.

Move c_getstr to fold-const.c

Upcoming patches to fold-const-call.c want to use c_getstr, which is

related to built-ins, and I'd rather not make fold-const-call.c depend
on builtins.c and builtins.c depend on fold-const-call.c, so this patch
moves the function to fold-const.c instead.

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Don't treat rint as setting errno

builtins.def says that rint sets errno, but it looks like this might
be a mistake.  C99 says that rint doesn't set errno and the builtins.c
expansion code doesn't try to keep errno up to date.

Perhaps this was because earlier versions of POSIX said that
rint sets errno on overflow:

        http://pubs.opengroup.org/onlinepubs/009695399/functions/rintf.html

However, this is another instance of the observation that "rounding
functions could never overflow" (because anything using exponents
that large is already integral).  The page above also says that
differences with C99 are unintentional and the ERANGE clause has
been removed from later versions of POSIX:

        http://pubs.opengroup.org/onlinepubs/9699919799/functions/rint.html

Also, the version of POSIX that lists ERANGE for rint does the same
for nearbyint:

        http://pubs.opengroup.org/onlinepubs/009695399/functions/nearbyintf.html

and we already treat nearbyint as not setting errno.  This too has been
clarified in later versions of POSIX:

        http://pubs.opengroup.org/onlinepubs/9699919799/functions/nearbyint.html

Add -fno-math-errno to gcc.dg/lto/20110201-1_0.c

At the moment the ECF_* flags for a gimple call to a built-in
function are derived from the function decl, which in turn is
derived from the global command-line options.  So if the compiler
is run with -fno-math-errno, we always assume functions don't set
errno, regardless of local optimization options.  Similarly if the
compiler is run with -fmath-errno, we always assume functions set errno.

This shows up in gcc.dg/lto/20110201-1_0.c, where we compile
the file with -O0 and use -O2 -ffast-math for a specific function.
-O2 -ffast-math is enough for us to convert cabs to sqrt as hoped,
but because of the global -fmath-errno setting, we assume that the
call to sqrt is not pure or const and create vops for it.  This makes
it appear to the gimple code that a simple sqrt optab isn't enough.

Later patches move more decisions about maths functions to gimple
and think that in this case we should use:

        y = sqrt (x);
        if (!(x >= 0))
            sqrt (x); // to set errno.

This is being tracked as PR68235.  For now the patch adds
-fno-math-errno to the dg-options for this test.

[PR67753] fix copy of PARALLEL entry_parm to CONCAT target_reg

In assign_parms_setup_block, the copy of args in PARALLELs from
entry_parm to stack_parm is deferred to the parm conversion insn seq,
but the copy from stack_parm to target_reg was inserted in the normal
copy seq, that is executed before the conversion insn seq.  Oops.

We could do away with the need for an actual stack_parm in general,
which would have avoided the need for emitting the copy to target_reg
in the conversion seq, but at least on pa, due to the need for stack
to copy between SI and SF modes, it seems like using the reserved
stack slot is beneficial, so I put in logic to use a pre-reserved
stack slot when there is one, and emit the copy to target_reg in the
conversion seq if stack_parm was set up there.

[Patch AArch64] Switch constant pools to separate rodata sections.

        Now that PR63304 is fixed and we have an option to address
any part of the memory using adrp / add or adrp / ldr instructions
it makes sense to switch out literal pools into their own
mergeable sections by default.

This would mean that by default we could now start getting
the benefits of constant sharing across the board, potentially
improving code size. The other advantage of doing so, for the
security conscious is that this prevents intermingling of literal
pools with code.

Wilco's kindly done some performance measurements and suggests that
there is not really a performance regression in doing this.
I've looked at the code size for SPEC2k6 today at -Ofast and
in general there is a good code size improvement as expected
by sharing said constants.

Tested on aarch64-none-elf with no regressions and bootstrapped
and regression tested in my tree for a number of days now.

gotest: fix handling of --goarch option

    I managed to add a new --goarch option to gotest without noticing that
    the script already had one.  Worse, they set different variables.
    Remove the old option in favor of the new one.
