3ccd57dac4 7007229: Fix warnings with VS2010 in compressedStream.cpp 
An interference between a fix for 6993125 and disabled optimization in compressedStream.cpp produces a warning with VS2010. Disable the warning for the code fragment for which the optimizations are disabled.

4a33afe6c4 7003125: precompiled.hpp is included when precompiled headers are not used 
Added an ifndef DONT_USE_PRECOMPILED_HEADER to precompiled.hpp. Set up DONT_USE_PRECOMPILED_HEADER when compiling with Sun Studio or when the user specifies USE_PRECOMPILED_HEADER=0. Fixed broken include dependencies.

d59d7ffc4a 6985015: C1 needs to support compressed oops 
This change implements compressed oops for C1 for x64 and sparc. The changes are mostly on the codegen level, with a few exceptions when we do access things outside of the heap that are uncompressed from the IR. Compressed oops are now also enabled with tiered.

34b016cb42 6982921: assert(_entry_bci != InvocationEntryBci) failed: wrong kind of nmethod 
Assertion fails during print compilation because nmethod::print_on() calls osr_entry_bci() without checking that the method is an osr method. The fix adds an appropriate check.
