[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.
