I've specially checked this case. DWARF register numbers are fixed for
all i386-based platforms (at least ones, supported by GCC). The only
special case seems to be cygwin/mingw, but I'll handle this case
separately.

Currently, I'm interested only in narrowing necessary bits (probably,
platform-dependent). Anyway, this won't hurt :)
