Anton Korobeynikov d27a258d2d Cleaned setjmp/longjmp lowering interfaces. Now we're producing right 
code (both asm & cbe) for Mingw32 target.
Removed autoconf checks for underscored versions of setjmp/longjmp.

Evan Cheng 24446e253a Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes. 
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.

Evan Cheng 02569d7355 - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just 
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill code.
