[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 neg;

void main()
{
    int i = 32;
    long l = 55;
    float f = 23;
    double d = 4;
    assert(-i == -32);
    assert(-l == -55);
    assert(-f == -23);
    assert(-d == -4);
}
