[svn r253] Removed -inlineasm option. inline asm is now enabled by default unless the new -noasm option is passed.

Tried adding a stack trace print when compiler crashes, not sure it's working though.
Changed data layouts to match that of llvm-gcc.
Fixed casting function pointers.
Added support checks in AsmStatement.
