Siddharth Bhat bb30377c5a [Polly] [GPUJIT] Set min size to 1 on CUDA allocation calls. [NFC]
Requesting size 0 allocations from `cuMalloc` / `cuMallocManaged` fails.
If there is a size 0 allocation that can be statically proved, the we
fail at PPCGCodeGeneration. This is because if size 0 allocation could
take place, we should not generate code that tries to use this array.

However, there are cases where we cannot statically prove this, and at
runtime we get a request for 0 bytes of memory. We choose to allocate
size 1 to allow the program to continue running.
