The patch also moves fold_fma too, with the same prototype. The long-term

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
type of a call expression is always traversed.

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.
