calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.

Get rid of yesterday's code to fix the register usage during isel.
Select the new DAG nodes to machine instructions.  The new pre-alloc pass
to choose adjacent registers for these results is not done, so the
results of this will generally not assemble yet.

2) RIP addressing: Use SIB bytes for absolute relocations where RegBase=0, 
IndexReg=0.
3) The JIT can get the real address of cstpools and jmptables during
code emission, fix that for object code emission

Factor some of the constants+context related code out into a separate header, to make LLVMContextImpl.h
not hideous.  Also, fix some MSVC compile errors.

for parameter packs.

In addition, introduce logic to enter the appropriate context for
subexpressions that are not potentially evaluated.

For other VLDn and VSTn operations, we need to list the multiple registers
explicitly anyway, so there's no point in special-casing this one usage.

 - Fix variant flattening when the variant embeds an operand reference.

 - Ignore instructions which reference an operand multiple times (e.g., "xorb

information about the error (it also exposes the numeric value of errno).
