[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.

module union1;

pragma(LLVM_internal, "notypeinfo")
union U
{
    float f;
    int i;
}

void main()
{
    float f = 2;
    U u = U(f);
    assert(u.i == *cast(int*)&f);
}
