If the address of the swapped memory location is known at compile time,
we can check its alignment at no runtime cost and use lswapl instead.

Should be safe since cpswap isn't used on pointers.

The original macros are retained (instead of replacing them with inline
functions) because of implicit type promotion. That is, an int16 passed
to an inline function taking int32 would be implicitly promoted to int32
without a warning.

Swapping the wrong size was never caught because swap{l,s} are macros.
It's clear in the case of Xext/xres.c, that the author believed
client_major/minor to be CARD16 from looking at the code in the first
hunk.
v2: dmx.c fixes from Keith.

These symbols were not renamed when they were added to libfb:
# nm -D libwfb.so | grep ' fb'
