RFR (XS): 8043207: Add const to Address argument for Assembler::swap

[Mikael Vidstedt]

Since this is a build problem the testing pretty much comes with 
building on the relevant platforms, which all pass with the fix in place.

Cheers,
Mikael

Some of the usages of the swap method pass a const argument, and when compiling with gcc the const-ness mismatch means the method cannot be resolved which in turn means a compilation error. This is for jdk7u (only) - the relevant code has been rewritten in jdk8+ to no longer have this problem.
