Anyext tweaks for x86. When extloading a value to i32 or i64, choose
...
instructions that define the full 32 or 64-bit value. When anyexting
from i8 to i16 or i32, it's not necessary to zero out the high
portion of the register.

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.
