changed: UInt::SubInt() in no-asm code is a little faster now
changed: small cosmetic changes in commentaries
deleted: some debug #ifdef's from UInt::Div() (in no-asm code)

sometimes when using -O2 or -O3 GCC doesn't set correctly
the stack pointer (actually the stack is used for other things)
and you can't use instructions like push/pop in assembler code.
All the asm code in x86_64 have been rewritten, now instructions
push/pop are not used, other thing which have access to stack
(like "m" (mask) constraints in Rcl2 and Rcr2) have also gone away,
now the library works well with -O2 and -O3 and the asm code
is a little faster

all the methods which are using assembler code have been
rewritten to no-asm forms, now we have:
1. asm for x86 file: ttmathuint_x86.h
2. asm for x86_64 file: ttmathuint_x86_64.h
3. no asm file: ttmathuint_noasm.h
(it's used when macro TTMATH_NOASM is defined)
The third form can be used on x86 and x86_64 as well and
on other platforms with a little effort.
(Temporarily I left there some '#ifdef's for debugging.)
