b1f67fbca0 SmallerC: generate smaller & faster code; bugfixes 
Improvements:
- use registers more efficiently
- eliminate some register copies and stack manipulations
- promote left operands to right immediate operands
- improve simple assignments to auto/static vars
- use bltz, blez, bgtz, bgez
- change mul/divu (by powers of 2) to sll/srl/and
- use seb, seh for sign extension instead of sll/sra
- overall generate a bit tighter, faster and more readable asm code

Fixes:
- >>= should be unsigned when the left operand is unsigned int.
The right operand isn't important here.
- very subtle bug in e.g. void f(){int a; &a+1;/*wrong value of &a+1*/}

Other:
- include stdarg.c and skeleton.c in /share/example/Makefile

00269e9387 Smaller C fixes and improvements: 
- move va_list type detection under #ifdef as it's rarely needed anyway
- allow up to 254 characters in a string literal
- generate a warning when an integer is passed instead of a pointer (and
vice versa) as a function parameter (pass -Wall for this)
- when printing an unexpected token, print identifier tokens instead of
'<tokIdent>'
- fix: allow most control characters inside '' and ""
- fix handling of -I<path> and -SI<path>
- switch() now supports Duff's device
- for() now supports declarations in its first clause as in C99/C++
