Optimize unrolled scanning for MSVC
While gcc and clang can eliminate dependency on s in the inner loop of PUGI__SCANWHILE_UNROLL, MSVC emits a series of register increments. Rewriting the code to explicitly remove the dependency keeps similar codegen on gcc/clang but improves codegen on MSVC for a 10% performance boost. Also use unrolled scanning in text_output_escaped (2% faster). git-svn-id: https://pugixml.googlecode.com/svn/trunk@1048 99668b35-9821-0410-8761-19e4c4f06640
