Retoss private/public stuff.
Make copy ctor and operator= private.

Fix (mem) <-> low 64-bits of xmm bugs pointed out by David Greene. Mac OS X Leopard assembler recognizes movq.

endianness of the target not of the host.  Done by the
simple expedient of reversing bytes for primitive types
if the host and target endianness don't match.  This is
correct for integer and pointer types.  I don't know if
it is correct for floating point types.

Fix ctlz and cttz. llvm definition requires them to return number of bits in of the src type when value is zero.

All MMX shift instructions took a <2 x i32> vector as the shift amount parameter. Change this to be <1 x i64> instead, which matches the assembler instruction.

still be done in the LLVM code generator. And update the summary for the
X86 target.

Let: %q = GEP %p, X, ...
If %p is a GEP, we can chase baseptr further, only if X==0.

Remove ugly and horrible code.  It's not necessary for correctness, and can be added back later if it causes code quality issues.

Implicit def instructions, e.g. X86::IMPLICIT_DEF_GR32, are always re-materializable and they should not be spilled.

put it in a new header System/Host.h instead.
Instead of getting the endianness from configure,
calculate it directly.
