Make AllocInfo's Instruction an int, so that we can overload it for arguments.
(Instruction #-1's operands = argument list).

Fix some spelling and grammar.

Update the profiling section

Switch to using edge profiling information as the basic source of profile info
from using basic block counts.

Switch over to using edge profile information as the basic profiling representation,
from basic block counts.

Refactor implementations

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12240 91177308-0d34-0410-b5e6-96231b3b80d8

We don't want to make this a pure interface, as it makes all implementors
bear the burden of implementing what will be all exactly the same methods.
They just want to provide the information in differing ways.

Rearrange some methods, implement the dominates method

Import the trace class from the reoptimizer

Default to using edge counts

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12234 91177308-0d34-0410-b5e6-96231b3b80d8

Annotate functions with edge counts as well, if they are available.

If we have edge counts, we can produce block counts.  I've verified that
using an edge profile to produce block counts gives the exact same numbers
as using a block count directly.

Adjust to new interface
