so that lwarx and stwcx are always executed the same number of times.
This is important for performance, I'm told.

and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.

infinite loop.

Fix write() when the string being written is larger than the buffer.  This broke various ObjC testcases
with very long symbol names.

1. x86-64 byval alignment should be max of 8 and alignment of type. Previously the code was not doing what the commit message was saying.
2. Do not use byte repeat move and store operations. These are slow.

Fix ComputeMaskedBits to handle phis correctly.  We need to take the
minimum of the known zeros.

This unbreaks explicit reg vars inside JIT, which are
implemented in such hacky way :)

getelementptr instructions.

Implement operator<< in terms of basic types rather than [u]int*_t, which is better for portability.  There might be some way to factor this all with metaprogramming magic, but I'm not sure how offhand.
