0dc93264b1 Generalize SROA to allow the first index of a GEP to be non-zero. Add a 
missing check that an array reference doesn't go past the end of the array,
and remove some redundant checks for in-bound array and vector references
that are no longer needed.

4e30207029 Implement PR5795 by merging duplicated return blocks. This could go further 
by merging all returns in a function into a single one, but simplifycfg 
currently likes to duplicate the return (an unfortunate choice!)

cd79ebb23c The phi translated pointer can be computed when returning a partially cached result 
instead of stored.  This reduces memdep memory usage, and also eliminates a bunch of
weakvh's.  This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x)
on a different machine than earlier.

fc4c238bd5 Add more plumbing. This time in the LowerArguments and "get" functions which 
return partial registers. This affected the back-end lowering code some.

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

64d9eb0c06 Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint. 
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.

88d8eb621b Add more plumbing to assign ordering to SDNodes. Have the "getValue" method 
assign the ordering when called. Combine some of the ordering assignments to
keep things simple.

8bd3f74d82 Add a fastpath to Load GVN to special case when we have exactly one dominating 
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.

299ec7d3e7 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.

eb77079db5 Remove special-case SROA optimization of variable indexes to one-element and 
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.
