stop the CBE from using Mangler::appendMangledName, which is a private function, it is mangling types, which don't matter how they are done.

to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

This is plumbing, so we don't have a use of it yet. More to come, etc.

additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

descriptive.  Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it.  Without doing this,
we are required to always use the same suffix for a global that gets 
mangled.  This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.
