743922ea75 Fold immediates into X86 shifts with fast isel. This generates: 
sarl    $3, %ecx

instead of:

movl    $3, %ecx
sarl    %cl, %edx

This shrinks fast isel 176.gcc by about 2000 instructions (.3%)

3589308f37 Address-mode folding for X86FastISel. It's pretty basic, but it 
catches a fair number of common cases. Note that this currently
causes Fast-ISel to leave behind lots of dead instructions.
Those will be dealt with in subsequent commits.

b5b6ec6488 FastISel: For calls, prefer using the callee's address as a constant 
over having it in a register. And wait until after checking type
legality before requesting that the callee address be placed in a
register. Also, fix support for calls with void return type.

This speeds up fast-isel isel time by about 15% and reduces
instruction counts by about 3% overall on certain testcases. It also
changes many indirect calls to direct calls.

9468a9b6be - Change "ExternalSymbolSDNode" to "SymbolSDNode". 
- Add linkage to SymbolSDNode (default to external).
- Change ISD::ExternalSymbol to ISD::Symbol.
- Change ISD::TargetExternalSymbol to ISD::TargetSymbol

These changes pave the way to allowing SymbolSDNodes with non-external linkage.

Abicall was enabled even when static code model was provided

The correct behavior is to disable abicall when static is

095cc29f32 Define CallSDNode, an SDNode subclass for use with ISD::CALL. 
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.
