2. Move section switch printing to MCSection virtual method which takes a
   TAI.  This eliminates textual formatting stuff from TLOF.
3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and 
   TLOFELF::AtIsCommentChar.

of possibilities which correspond to intrinsics already used.

Also, redefined MatchRegisterName to just return the register value or a
sentinel, to simplify the generated code.

A TAI hook is appropriate in this case because this is just an
asm syntax issue, not a semantic difference. TLOF should model
the semantics of the section.

give the impls an object-file-specific name.  In the future
they can take different arguments etc.

now that they create *all* the sections.

since they are in 64 bit mode with i64immSExt32 imms. JIT is not affected since 
it handles both word absolute relocations in the same way

 - This doesn't actually improve the algorithm (its still linear), but the
   generated (match) code is now fairly compact and table driven. Still need a
   generic string matcher.

 - The table still needs to be compressed, this is quite simple to do and should
   shrink it to under 16k.

 - This also simplifies and restructures the code to make the match classes more
   explicit, in anticipation of resolving ambiguities.

so I generalized the class for VTRN in the .td file to handle all 3 of them.

directly from the intrinsics produced by the frontend.  If it is more
convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.
