1. DUPMAX is defined in regcomp.c, no need to redefine it in regutils.
2. MSVC doesn't like snprintf, use _snprintf instead.

 - I think there are more instances of this, but I think they are fixed in Dan's
   incoming patch. This one was preventing me from doing a bugpoint reduction
   though.

the former will print out the contents of the constant range that failed.

This can break when there are implicit conversions from types raw_ostream
understands but std::ostream doesn't, but it increases the number of cases that

linear scan reg alloc.  This fixes a problem I ran into where extracting
a function from a larger file caused the generated code to change (masking
the problem I was trying to debug) because the allocator behaved differently.

This changes the results for two X86 regression checks.  stack-color-with-reg
is improved, with one less instruction, but pr3495 is worse, with one more
copy.  As far as I can tell, these tests were just getting lucky or unlucky,
so I've changed the expected results.

Do not use DenseMap operator[] because it inserts new entry if lookup fails. Use find() to check an entry in a DenseMap first.

and the lexer.  Then changed the lexer to use CommentString from MCAsmInfo
instead of a literal '#' character.
