Also patch up some places I missed before in the "get" functions.

SDNodes. This time in the load/store and limited-precision code.

This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals.

load to avoid even messing around with SSAUpdate at all.  In this case (which
is very common, we can just use the input value directly).

This speeds up GVN time on gcc.c-torture/20001226-1.c from 36.4s to 16.3s,
which still isn't great, but substantially better and this is a simple speedup
that applies to lots of different cases.

Fix a bug in !subst where TableGen would go and resubstitute text it had
just substituted.  This could cause infinite looping in certain
pathological cases.

Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

two-element arrays.  After restructuring the SROA code, it was not safe to
do this without adding more checking.  It is not clear that this special-case
has really been useful, and removing this simplifies the code quite a bit.

the underlying PHI node insertion issue in SSAUpdate is fixed.
