Tweak the exporter for inlinable function bodies to work around a
problem with importing of function calls whose function expressions
are not simple function names. In the bug in question, the function
body exporter was writing out a function call of the form
(*(*FuncTyp)(var))(arg)
which produced an export data representation of
*$convert(<type 5>, var)(x)
which is hard to parse unambiguously. Fix: change the export data
emitter to introduce parens around the function expression for more
complex calls.
Testcase for this bug is in CL 197217.

It was easier to add the SVE ACLE support without enumerating every
function at build time. This in turn meant that it was easier if the
SVE builtins occupied a distinct numberspace from the existing AArch64
ones, which *are* enumerated at build time. This patch therefore
divides the built-in functions codes into "major" and "minor" codes.
At present the major code is just "general", but the SVE patch will add
"SVE" as well.
Also, it was convenient to put the SVE ACLE support in its own file,
so the patch makes aarch64.c provide the frontline target hooks directly,
forwarding to the other files for the real work.
The reason for organising the files this way is that aarch64.c needs
to define the target hook macros whatever happens, and having aarch64.c
macros forward to aarch64-builtins.c functions and aarch64-bulitins.c
functions forward to the SVE file seemed a bit indirect. Doing things
the way the patch does them puts aarch64-builtins.c and the SVE code on
more of an equal footing.
The aarch64_(general_)gimple_fold_builtin change is mostly just
reindentation.

For SVE, we'd like the frontends to check calls to target-specific
built-in functions in the same way that they already do for "normal"
builtins. This patch adds a target hook for that and extends
check_builtin_function_arguments accordingly.
A slight complication is that when TARGET_RESOLVE_OVERLOADED_BUILTIN
has resolved an overload, it can use build_function_call_vec to build
the call to the underlying non-overloaded function decl. This in
turn coerces the arguments to the function type and then calls
check_builtin_function_arguments to check the final call. If the
target does find a problem in this final call, it can be useful
to refer to the original overloaded function decl in diagnostics,
since that's what the user wrote.
The patch therefore passes the original decl as a final optional
parameter to build_function_call_vec.
