Another patch to extend uses of built_in_function to combined_fn, this time
in tree-vrp.c.

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

gcc/
	* tree-vrp.c: Include case-cfn-macros.h.
	(extract_range_basic): Switch on combined_fn rather than handling
	built-in functions and internal functions separately.

From-SVN: r230479

This patch generalises fold-const.[hc] routines to use combined_fn
instead of built_in_function.  It also updates gimple-ssa-backprop,c
since the update is simple and it avoids churn on the call to
negate_mathfn_p.

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

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>",
so the patch follows hash_map in using the types given by the
traits as the key.  This is a no-op for current users of hash_set.

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

gcc/
	* Makefile.in (HASH_TABLE_H): Add GGC_H.

This patch adds internal function equivalents of all the INT_FN functions.
Unlike the math functions, these functions never set errno and the internal
functions should be exactly equivalent to the built-in ones.  The reason
for defining the internal functions is so that we can extend the
functionality to other modes, in particular vector modes.

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

	* internal-fn.def (DEF_INTERNAL_INT_FN): New macro.

From-SVN: r230475

This patch adds internal functions for simple FLT_FN built-in functions,
in cases where an associated optab already exists.  Unlike some of the
built-in functions, these internal functions never set errno.

LDEXP is an odd-one out in that its second operand is an integer.
All the others operate on uniform types.

The patch also adds a function to query the internal function associated
with a built-in function (if any), and another to test whether a given
gcall could be replaced by a call to an internal function on the current
target (as long as the caller deals with errno appropriately).

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

From-SVN: r230474

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.)

I'm working on a patch series that needs to be able to treat built-in

a given CALL_EXPR or gcall.

Since r230164, in PR68330 combine ends up with a sign_extend of an
lshiftrt by some constant, and it does not know to morph that into a
zero_extract (the extend will always extend with zeroes).  I think
it is best to let simplify-rtx always replace such a sign_extend by
a zero_extend, after which everything works as expected.
