Fix regression in r736
r736 added intra RD refinement to B-frames; however, it is possible for subme=7 to be used without b-rdo.
This means intra RD isn't run, and therefore it is possible for intra chroma analysis to not have been run, since update_cache was never called for an intra block, and chroma ME is not required even at subme=7.
r801, which removed a memset, made this worse because previously the chroma prediction mode was at least initialized to zero; now it was not initialized at all.
Therefore, --no-chroma-me, --subme 7, and no --b-rdo had the potential to crash.
This change restricts intra RD refinement to only be run when --b-rdo is enabled (sensible to begin with), thus preventing a crash in this case.

many changes to which asm functions are enabled on which cpus.
with Phenom, 3dnow is no longer equivalent to "sse2 is slow", so make a new flag for that.
some sse2 functions are useful only on Core2 and Phenom, so make a "sse2 is fast" flag for that.
some ssse3 instructions didn't become useful until Penryn, so yet another flag.
disable sse2 completely on Pentium M and Core1, because it's uniformly slower than mmx.
enable some sse2 functions on Athlon64 that always were faster and we just didn't notice.
remove mc_luma_sse3, because the only cpu that has lddqu (namely Pentium 4D) doesn't have "sse2 is fast".
don't print mmx1, sse1, nor 3dnow in the detected cpuflags, since we don't really have any such functions. likewise don't print sse3 unless it's used (Pentium 4D).
