294e633d95 add a traits class for SmallPtrSet that allows us to stick things that are 
"basically pointers" into it.

71bb115e1c Reapply r66415, which was reverted in r66426 for 
causing a bootstrap failure.  Bootstraps here on
x86-32-linux and x86-64-linux.  Requested by the
author Gabor Greif who says that a bug that might
have been causing the failure has since been fixed.

9a8e64c76f Give sentinel traits the right to determine the policy where the sentinel is kept. 
This should result in less indirect memory accesses, less dead writes and tighter code.

9b51fe4ab1 Introduce a new technique for merging BasicBlock with Instruction sentinel by superposition. 
This looks dangerous, but isn't because the sentinel is accessed in special way only,
namely the Next and Prev fields of it, and these are guaranteed to exist.

504ba4c98b Fix a bug in BitVector.h. All assignment operations (except the usual 
assignment operator) were returning a copy of the bit vector, instead of a
reference! This old semantics probably did not meet the expectations.
With this patch, chained assignments happen to the right object.

a5699a1e8b Do not use host floating point types when emitting 
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

71f808dfa2 * Don't explicitly cast "0" to "void*". This doesn't work well with specialized 
StringMapEntryInitializer classes. Leave it for the compiler to figure out what
 the type is and what "0" should be transformed into.
