Initialize results of buffer.load.* ops to zero. (#14589)
This works around warnings about maybe uninitialized values generated by
gcc by initializing result variables to zero before their addresses to .
Older versions of gcc seem to be unable to follow writes to
uninitialized values across conditional control flow like
```C
A:
int result;
int *resultPtr;
bool failure;
...
X:
/* result = 0; */ // Zero initialization added in this PR
resultPtr = &result;
failure = tryWrite(resultPtr, ...); // resultPtr is written iff this returns false
if (failure)
goto Y;
else
goto Z;
Y:
return;
Z:
use(result);
```IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!
