- Fixed Single.ToString() on special cases (infinities, NaN and 0) and aumented the range of printable values - Fixed Double.ToString(): it always printed "Double Overrange" for a bug in opcode ldarga - Fixed opcode ldarga: the displacement of the argument variable was off of 4 bytes - Fixed opcodes shr, shr_un and shl when the shift was more that 32 bytes, added to BCL relative tests - Added BLC tests regarding BitConverter and unsafe code - Moved the meat of the code of Single.ToString() and Double.ToString() to the class StringHelper together with the analogous methods for numer types - Re-added _floatsignbit to CosmosAssembler.cs so the neg test should not fail anymore - Removed all code relative to x87 that I had left under #if false - Clean up
