6e5b4c609c 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%)

71b1f15917 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.

5fbd0e95f3 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.

1a240c8033 - 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 
in the command line.
The correct behavior is to disable abicall when static is
specified.

changing to the shorter names if others prefer it.

3450a8252f 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.

10e1cf3df2 The version of AtomicSDNode::AtomicSDNode used (only) for 
cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the
x86 BE had a compensating reversal, which is removed here.
PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

bd15e330d0 For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.

53ce5fa5ce Remove code that pad number of bytes to pop for X86_FastCall CC. The code doesn't do the "aligning" for Cygwin, Mingw, and Windows. But aligning it on Darwin and Linux breaks gcc compatibility. That ruled out all the platforms we support!

18cc2a26df Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.
