LLVM 15 switched to opaque pointers by default and no longer supports typed pointers.
Remove deprecated LLVM calls and update test.

LLVM automatically add an numeric suffix for names
automatically created. So, if intermediate names must
be created for a pseudo whose name was, for example, "%R4",
these new names will be "%R41", "%R42".
This is quite annoying because we can't make the distinction
between these names and the original names, (maybe of some other
pseudos whose names were "%R41" & "%R42).
Change this by adding a "." at the end of each name, as this will
then allow to see what the original name was.

The linearized code, sparse's IR, have no use of C's complex type
system. Those types are checked in previous phases and the pseudos
doesn't have a type directly attached to them as all the needed
typing info info are conveyed by the instructions.
In particular, PSEUDO_VAL (used for integer and address constants)
are completely typeless.
There is a problem with this when calling a variadic function
with a constant argument as in this case there is no type in the
function prototype (for the variadic part, of course) and there is
no defining instructions holding the type of the argument.
Fiw this by using the type of the arguments explicitly given
in the OP_CALL instructions.
