Split each select function for a particular opcode into multiple ones. One
...
per possible ValueType of the node. e.g. Select_add is split into Select_add_i8,
Select_add_i16, etc.
For opcodes which do not produce a non-chain result, it is split on the
ValueType of its first non-chain operand. e.g. Select_store.
On X86 / Mac OS X, Select_store used to be the largest function. It had a stack
frame size of 8.5k. Now the largest one is Store_i32 with a frame size of 3.1k.

Reduce instruction selection code size and stack frame size by factoring

code that emit target specific nodes into emit functions that are uniquified
and shared among selection routines.
e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame
size of Select_store from ~13k down to ~8k.
This is the first step. Further work to enable more sharing will follow.

Don't require src/dst patterns to be able to fully resolve their types,

def : Pat<(extload xaddr:$src, i8),

Now that iPTR is a fully resolved type. We end up losing the type check for

patterns that look like this:
