a global with that gets printed with the :mem modifier.  All operands to lea's 
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this.  There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).

This also makes the use of EBX explicit in the operand list in the 32-bit, 
instead of implicit in the instruction.

Introduce Decl::getSourceRange() which, like Stmt::getSourceRange(), represents the range that the declaration covers.

Add initial support for NamespaceDecl, VarDecl, and FunctionDecl:
-NamespaceDecl range is from name to '}'
-VarDecl is from name to possible init expression
-FunctionDecl is from name to last parameter name or to end of its function body.

SCEVUnknowns with identical Instructions to be equal. This allows
it to analze cases such as the attached testcase, where the front-end
has cloned the loop controlling expression. Along with r73805, this
lets IndVarSimplify eliminate all the sign-extend casts in the
loop in the attached testcase.

Add debugging code to test for various locking faux-pas's, when running in single threaded mode.  This should help improve testing coverage for
threading support, without having extensive actually concurrent clients yet.

Revert r73790, and replace it with a significantly less ugly solution.  Rather than trying to make the global reader-writer lock work,
create separate recursive mutexes for each value map.  The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.
