Extend tree-call-cdce to calls whose result is used

For -fmath-errno, builtins.c currently expands calls to sqrt to:

        y = sqrt_optab (x);
        if (y != y)
          [ sqrt (x); or errno = EDOM; ]

The drawbacks of this are:

- the call to sqrt is protected by the result of the optab rather
      than the input.  It would be better to check __builtin_isless (x, 0),
      like tree-call-cdce.c does.

- the branch isn't exposed at the gimple level and so gets little
      high-level optimisation.

- we do this for log too, but for log a zero input produces
      -inf rather than a NaN, and sets errno to ERANGE rather than EDOM.

This patch moves the code to tree-call-cdce.c instead, with the optab
operation being represented as an internal function.  This means that
we can use the existing argument-based range checks rather than the
result-based checks and that we get more gimple optimisation of
the branch.

Previously the pass was only enabled by default at -O2 or above,
but the old builtins.c code was enabled at -O.  The patch therefore
enables the pass at -O as well.

The previous patch to cfgexpand.c handled cases where functions
don't (or are assumed not to) set errno, so this patch makes
the builtins.c code dead.

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

Short-cut generation of simple built-in functions

This patch short-circuits the builtins.c expansion code for a particular
gimple call if:

Add null identifiers to genmatch

This patch adds a null identifier that can never match anything and
can never be generated.  It is only valid in operator lists and fors.
Later patches will add uses of it.

The idea is to allow operator lists for maths functions that have
four entries:

- float built-in
- double built-in
- long double built-in
- internal function

Not all maths functions have an associated internal function,
and for those the final operator will be "null".  Any simplification
that tries to use a null substitution will be skipped.

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

Add genmatch support for internal functions

This patch makes genmatch match calls based on combined_fn rather
than built_in_function and extends the matching to internal functions.
It also uses fold_const_call to fold the calls to a constant, rather
than going through fold_builtin_n.

In order to slightly simplify the code and remove potential
ambiguity, the patch enforces lower case for tree codes
(foo->FOO_EXPR), caps for functions (no built_in_hypot->BUILT_IN_HYPOT)
and requires an exact match for user-defined identifiers.  The first two
were already met in practice but there were a couple of cases where
operator lists were defined in one case and used in another.

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

Add gencfn-macros.c

This patch automatically generates case macros such as:

        CASE_CFN_SQRT

for each {F,,L} floating-point built-in function and each {,L,LL,IMAX}
integer built-in function.  The macros match the same built-in
functions as CASE_FLT_FN and CASE_INT_FN but in addition include
the associated internal function, if any.

The idea is to make sure that users of combined_fn don't need to know
which built-in functions have internal-function equivalents.  If we add
a new function to internal-fn.def, all combined_fn users should pick it
up automatically.

The generator wants to use "hash_set <nofree_string_hash>",

Add basic support for direct_optab internal functions

This patch adds a concept of internal functions that map directly to an
optab (here called "direct internal functions").  The function can only
be used if the associated optab can be used.

We currently have four functions like that:

- LOAD_LANES
- STORE_LANES
- MASK_LOAD
- MASK_STORE

so the patch converts them to the new infrastructure.  These four
all need different types of optabs, but future patches will add
regular unary and binary ones.

In general we need one or two modes to decide whether an optab is
supported, depending on whether it's a convert_optab or not.
This in turn means that we need up to two types to decide whether
an internal function is supported.  The patch records which types
are needed for each internal function, using -1 if the return type
should be used and N>=0 if the type of argument N should be used.

(LOAD_LANES and STORE_LANES are unusual in that both optab modes
come from the same array type.)

Add a combined_fn enum

I'm working on a patch series that needs to be able to treat built-in
functions and internal functions in a similar way.  This patch adds a
new enum, combined_fn, that combines the two together.  It also adds
utility functions for seeing which combined_fn (if any) is called by
a given CALL_EXPR or gcall.

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

* tree-core.h (internal_fn): Move immediately after the definition
