If a vr is already marked alive in a bb, then it has PHI uses that are visited earlier, then it is not killed in the def block (i.e. not dead).

Added a "ConstantNotEq" map to ValueState (and added necessary typedefs and factory objects to ValueStateManager).

unique ImutAVLTree* for profiling.

Modified ImutAVLTree:
 (1) changed ComputeHash() to ComputeDigest() and
 (2) changed Profile() to use the computed digest and
 (3) modified insertion of IMutAVLTree into the FoldingSet owned by
     the ImutAVLTreeFactory object to use profiling instead of computing
     a direct hash.  This fixes a bug where our abuse of the FoldingSet would
     not work when the FoldingSet was resized.

structure that can contain several maps, not just one.

llvm-svn: 46744

Type*'s can change as types are refined, so we can't use them as a stable key in
the map.  Decls don't change, so use them instead.

This patch was written by Anders, but he's too shy to commit it himself :)

was incorrectly simplifying "x == (gep x, 1, i)" into false, even 
though i could be negative.  As it turns out, all the code to 
handle this already existed, we just need to disable the incorrect
optimization case and let the general case handle it.

vec_ext_v4si builtins.  This is a hack; they should
be defined here, then resolved in the X86 BE.
However there is enough other stuff missing in the
X86 BE for SSE41 that this will do for now.

Dwarf requires variable entries to be in the source order. Right now, since we are recording variable information at isel time this means parameters would appear in the reverse order. The short term fix is to issue recordVariable() at asm printing time instead.

inside this class.  The goal is to gradually separate more of the state
management from the state transformation.
