Move constant folds for maths functions to new file

The new routines operate on the built-in enum rather than on tree decls.
The idea is to extend this to handle internal functions too, with a
combined enum for both.

The patch also moves fold_fma too, with the same prototype.  The long-term
plan is to replace FMA_EXPR with an internal function, for consistency
with the way that things like SQRT will be handled.

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

    compiler: Traverse types of call expressions.

    https://gcc.gnu.org/PR67968 provides a test case that causes a gccgo
    crash on valid code.  The compiler failed to build the hash and equality
    functions required for a type descriptor.  The descriptor is for an
    unnamed type that is being returned by a function imported from a
    different package.  The unnamed type is being implicitly converted to an
    interface type by a return statement.  The fix is to ensure that the

runtime: If no split stacks, allocate stacks using mmap on 64-bit systems.

    When not using split stacks, libgo allocate large stacks for each
    goroutine.  On a 64-bit system, libgo allocates a maximum of 128G for
    the Go heap, and allocates 4M for each stack.  When the stacks are
    allocated from the Go heap, the result is that a program can only create
    32K goroutines, which is not enough for an active Go server.  This patch
    changes libgo to allocate the stacks using mmap directly, rather than
    allocating them out of the Go heap.  This change is only done for 64-bit
    systems when not using split stacks.  When using split stacks, the
    stacks are allocated using mmap directly anyhow.  On a 32-bit system,
    there is no maximum size for the Go heap, or, rather, the maximum size
    is the available address space anyhow.

Allow real_format to be passed to more real.h functions

Most real.h routines used machine modes to specify the format of
an operation and converted that to a float_format * internally.
Some also had alternative versions that accepted a float_format *.

In an upcoming patch it seemed more convenient for the callers
I was adding to use float_format directly, since the callers need
to examine the format themselves for other reasons.  This patch
therefore replaces the machine_mode arguments with a new class that
allows both machine modes and float_format pointers to be used.

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

gcc/
* real.h (format_helper): New.

Fix real_2expN mode arguments in fixed-value.c

fixed-value.c was passing a fixed-point mode to the floating-point
real_2expN routine.  That didn't cause a problem in practice because
all real_2expN did was check for decimal float modes, but it triggered
a failure with an upcoming patch.

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

gcc/
* fixed-value.c (check_real_for_fixed_mode, fixed_from_string)
(fixed_to_decimal, fixed_convert_from_real)
(real_convert_from_fixed): Fix mode arguments to real_2expN.

Robustify REAL_MODE_FORMAT

Make sure that REAL_MODE_FORMAT aborts if it is passed an invalid mode,
rather than stepping beyond the bounds of an array.  It turned out that
some code was passing non-float modes to the real.h routines.

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

gcc/
* real.h (REAL_MODE_FORMAT): Abort if the mode isn't a
SCALAR_FLOAT_MODE_P.
