Change function call information to be variable length. 

Before this change FunctionCallInfoData, the struct arguments etc for
V1 function calls are stored in, always had space for
FUNC_MAX_ARGS/100 arguments, storing datums and their nullness in two
arrays.  For nearly every function call 100 arguments is far more than
needed, therefore wasting memory. Arg and argnull being two separate
arrays also guarantees that to access a single argument, two
cachelines have to be touched.

Change the layout so there's a single variable-length array with pairs
of value / isnull. That drastically reduces memory consumption for
most function calls (on x86-64 a two argument function now uses
64bytes, previously 936 bytes), and makes it very likely that argument
value and its nullness are on the same cacheline.

Arguments are stored in a new NullableDatum struct, which, due to
padding, needs more memory per argument than before. But as usually
far fewer arguments are stored, and individual arguments are cheaper
to access, that's still a clear win.  It's likely that there's other
places where conversion to NullableDatum arrays would make sense,
e.g. TupleTableSlots, but that's for another commit.

Because the function call information is now variable-length
allocations have to take the number of arguments into account. For
heap allocations that can be done with SizeForFunctionCallInfoData(),
for on-stack allocations there's a new LOCAL_FCINFO(name, nargs) macro
that helps to allocate an appropriately sized and aligned variable.

Some places with stack allocation function call information don't know
the number of arguments at compile time, and currently variably sized
stack allocations aren't allowed in postgres. Therefore allow for
FUNC_MAX_ARGS space in these cases. They're not that common, so for
now that seems acceptable.

Because of the need to allocate FunctionCallInfo of the appropriate
size, older extensions may need to update their code. To avoid subtle
breakages, the FunctionCallInfoData struct has been renamed to
FunctionCallInfoBaseData. Most code only references FunctionCallInfo,
so that shouldn't cause much collateral damage.

This change is also a prerequisite for more efficient expression JIT
compilation (by allocating the function call information on the stack,
allowing LLVM to optimize it away); previously the size of the call
information caused problems inside LLVM's optimizer.

nargs and args[] hold the arguments being passed to the function.
Notice that all the arguments passed to a function (as well as its result
value) will now uniformly be of type Datum. As discussed below, callers
and callees should apply the standard Datum-to-and-from-whatever macros
to convert to the actual argument types of a particular function. The
value in arg[i] is unspecified when argnull[i] is true.
value in args[i].value is unspecified when args[i].isnull is true.
It is generally the responsibility of the caller to ensure that the
number of arguments passed matches what the callee is expecting; except
for callees that take a variable number of arguments, the callee will
typically ignore the nargs field and just grab values from arg[].
typically ignore the nargs field and just grab values from args[].
The isnull field will be initialized to "false" before the call. On
return from the function, isnull is the null flag for the function result:
if it is true the function's result is NULL, regardless of the actual
function return value. Note that simple "strict" functions can ignore
both isnull and argnull[], since they won't even get called when there
are any TRUE values in argnull[].

A nonstrict function is responsible for checking whether each individual

just "fcinfo->argnull[n]"). It should avoid trying to fetch the value

For float4, float8, and int8, the PG_GETARG macros will hide whether the

pass-by-reference then PG_GETARG_FLOAT8 expands to
