spec: get rid of all specifier MOD_XXX
Modifiers like MOD_CHAR, MOD_LONG, ... are used to keep track
of the size/rank of integers and floats. But this is problematic:
* they use 5 of the precious modifiers bits
* they're not really modifiers but the base of the primitive types
* a 'long double' has MOD_LONGLONG set
Change this by using instead the explicit notion of 'rank'.
The advanatges are:
* using only 3 bits (in struct symbol)
* free 5 modifier bits
* follow closely the definition & rules of the standard
* things like integer promotion are slightly simpler.
Note: this is somewhat experimental as I'm not yet convinced
that everything is correct (but the testsuite is OK
and gives the same result for a defconfig + allyesconfig
build of the kernel).
