1b65253da6 Require IVUsers after LCSSA, since LCSSA does not preserve IVUsers. 
This results in the pass manager running IVUsers only once for
indvars, instead of twice.

93990d775e After converting assert(0) to LLVM_UNREACHABLE we lost file/line location. 
Fix by making the LLVM_UNREACHABLE pass __FILE__ and __LINE__ to
llvm_unreachable.

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.

a342026504 Introduce a new LoopInfo utility function makeLoopInvariant, which 
works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

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.
