d752e0f7e6 Added invariant field to the DAG.getLoad method and changed all calls. 
When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

Define function getNextIntArgReg, which takes a register as a parameter and

precision floating point arguments are passed in two integer registers.

da7f5f1c1d Make changes to avoid creating nested CALLSEQ_START/END constructs, which aren't 
yet legal according to comments in LegalizeDAG.cpp:227. 

Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.

28b77e968d Add codegen support for vector select (in the IR this means a select 
with a vector condition); such selects become VSELECT codegen nodes.
This patch also removes VSETCC codegen nodes, unifying them with SETCC
nodes (codegen was actually often using SETCC for vector SETCC already).
This ensures that various DAG combiner optimizations kick in for vector
comparisons.  Passes dragonegg bootstrap with no testsuite regressions
(nightly testsuite as well as "make check-all").  Patch mostly by
Nadav Rotem.

26689ac37e New approach to r136737: insert the necessary fences for atomic ops in platform-independent code, since a bunch of platforms (ARM, Mips, PPC, Alpha are the relevant targets here) need to do essentially the same thing. 
I think this completes the basic CodeGen for atomicrmw and cmpxchg.
