Andrew Burgess 6f7664a9c3 gdb: Convert la_name and la_natural_name to methods
Convert the two language_data member variables la_name and
la_natural_name to virtual methods in language_defn struct called name
and natural_name respectively.

The virtual methods in the language_defn base class are pure virtual,
as every language must implement these, and as every language has a
unique name there's no sensible default here.

Given that every language must implement these methods I did wonder
about making this data passed into the base class constructor, but in
the end I went with the virtual method approach.  I'm open to changing
this approach if people prefer the constructor approach.

During updating the calls to language_defn::name I found in
add_set_language_command a place where we took la_name and then
capitalised the first letter to create a language name that could be
used in the documentation string.  I replaced this with a use of
natural_name instead as this seemed a better choice, in most cases
this will make no difference, as for most languages the natural_name
is just the name with the first character in upper case, but for some
languages, for example 'Open-CL' and 'Objective-C' this is not the
case.

In the case of asm_language the name is 'asm', while the natural_name
was previously 'assembly'.  I changed the natural name to 'Assembly',
this makes the documentation string case above cleaner, however, this
will change the MI output for -var-info-expression, where the 'lang'
field will change from 'assembly' to 'Assembly'.  It is possible this
could be a breaking change if a front-end is relying on the existing
name.

It's too hard, for example, to know whether one is looking at a mangled
Go symbol or not, and their are ambiguities, e.g., the demangler may
get passed *any* symbol, including symbols from other languages
and including symbols that are already demangled.
One thought is to at least add an _G prefix.
