Change exceptions.h functions to use gdb::function_view

This changes some functions in exceptions.h to use gdb::function_view,
then fixes up the fallout. This lead to some surprising places, like
a function pointer in target_so_ops.

While writing this I found that catch_exception_ftype was unused, so I
removed this.

Note that I did not compile the windows-nat.c change, so I don't know
if it works.

Regression tested by the buildbot.

Complete tdep move to convert_typed_floating

Many tdep files need to perform conversions between two floating-point
types, usually when accessing FP registers. Most targets now use the
convert_typed_floating helper routine to do so. However, a small number
still use the old method of converting via a DOUBLEST. Since we want
to get rid of DOUBLEST, these targets need to be moved to the new
method as well.

The main obstacle is that for convert_typed_floating we need an actual
*type*, not just a floatformat.

In arm-tdep.c, this is very straightforward, since there is already a
type using the ARM extended floatformat.

For sh-tdep.c and sh64-tdep.c, no such type already exists, so I've
added one to the gdbarch_tdep struct as done on other targets.

Simplify floatformat_from_type

For historical reasons, the TYPE_FLOATFORMAT element is still set to hold
an array of two floatformat structs, one for big-endian and the other for
little-endian. When accessing the element via floatformat_from_type,
the code would check the type's byte order and return the appropriate
floatformat.

However, these days this is quite unnecessary, since the type's byte order
is already known at the time the type is allocated and the floatformat is
installed into TYPE_FLOATFORMAT. Therefore, we can just install the correct
version here.

Also, moves the (now trivially simple) floatformat_from_type accessor to
gdbtypes.{c,h}, since it doesn't really need to be in doublest.c now.

Make init_type/arch_type take a size in bits

This changes the interfaces to init_type and arch_type to take the
type length in bits as input (instead of as bytes). The routines
assert that the length is a multiple of TARGET_CHAR_BIT.

For consistency, arch_flags_type is changed likewise, so that now
all type creation interfaces always use length in bits.

All callers are updated in the straightforward manner.

The assert actually found a bug in read_range_type, where the
init_integer_type routine was called with a wrong argument (probably
a bug introduced with the conversion to use init_integer_type).
