MipsAdd SDNode created to add support to an Add opcode which supports input flag
Added an instruction itinerary to all instruction classes
Added branches with zero cond codes
Now call clobbers all non-callee saved registers
Call w/ register support added
Added DelaySlot to branch and load instructions

that read a module but don't materialize most of the functions (e.g. 62K for 252.eon).

"return of stack addresses."  ParseReturnStmt now calls CheckReturnStackAddr
to determine if the expression in the return statement evaluates to an
address of a stack variable.  If so, we issue a warning.

The AC_CHECK_HEADER macro was used instead of AC_CHECK_HEADERS. The former does
not automatically add a #define to the configure variables while the latter
does. Consequently, the HAVE_PTHREAD_H symbol was not defined which caused the
Mutex.cpp file to compile to an empty implementation.

Update test: dynamic_stackalloc size *must* be rounded to ensure stack ptr be left in a valid state.

If dynamic_stackalloc alignment is > stack alignment, first issue an instruction to align the stack ptr before the decrement.

- If a dynamic_stackalloc alignment requirement is <= stack alignment, then the alignment argument is ignored.
- *Always* round up the size of the allocation to multiples of stack
alignment to ensure the stack ptr is never left in an invalid state after a dynamic_stackalloc.

Fixed Sema::CheckEqualityOperands() and Sema::CheckRelationalOperands() to deal more 
thoughtfully with incompatible pointers. This includes:

- Emit a diagnostic when two pointers aren't compatible!
- Promote one of the pointers/integers so we maintain the invariant expected by the 
code generator (i.e. that the left/right types match).
- Upgrade the pointer/integer comparison diagnostic to include the types.

two's complement bignum arithmetic.  They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

1. Eliminate redundant error messages. LinkInFile and LinkInArchive
   already call the error() method in each case so there's no use
   telling the user again that an item couldn't be linked in.

2. Improve the formatting of error messages (separating content).

3. Change the wording for the warning about unrecognized files. Make
   it clear that the file is being ignored.
