62990bafa3 Allow inline asm nodes with empty bodies inside JIT.
This unbreaks explicit reg vars inside JIT, which are
implemented in such hacky way :)

5cc101ec89 getelementptr doesn't work on x86-64 yet, because it
has MOV64ri32 and no plain MOV64ri.

7a0e6593d0 MVT::getMVT uses iPTR for pointer types, while we need the actual
intptr_t type in this case. FastISel can now select simple
getelementptr instructions.

89a1a85913 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.

0bfa1bfbff Move the handling of ANY_EXTEND, SIGN_EXTEND_INREG, and TRUNCATE
out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.
