5c0ba804c0 Rename Mangler linkage enums to something less gross.

3d10a5a757 Add plumbing for the `linker_private' linkage type. This type is meant for
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

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

9d5511b7db eliminate the Mangler::PreserveAsmNames bit, the sole client of this
can do it perfectly well itself.

b8158acc23 Reapply my previous asmprinter changes now with more testing and two
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.

03e9dd9ffa Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr"
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".

1cda87c3a0 Change the internal interface to makeNameProper to take a bool that
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.

59ecdfbee3 rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more
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.

7107c3badf For PR780:
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore

3. Make each of the tools with --load options include LinkAllVMCore.h

d35f605613 Allow per-character control over what target assemblers allow in symbol
names.  This also changes the default to allow all of "$_." in addition
to letters and numbers as symbol names.  If you don't want this, use
markCharUnacceptable to remove one of these or markCharAcceptable to add
to the set.  This corresponds with what GAS accepts by default.
