* shared/vectors/vectors.h, shared/vectors/vectors.S,
shared/vectors/vectors_init.c: Reduced size of default
prologue (some exceptions, e.g., altivec unavail.) are only
0x20 bytes apart. Also introduced a modified prologue
that switches r0..r3 shadowing off (r0..r3 undefined
on certain 603e variants when incurring a TLB miss).
