ISPC File Issue

[Stefan-Mada]

Any ISPC file I compile crashes in supervec with the same stacktrace, here is one example:

Source file (ISPC code):

export void greyScaleISPC(uniform unsigned int8 vin[], uniform unsigned int8 vout[],
                   uniform int length) {
    
	foreach(index = 0 ... length)
		vout[index] = vin[index];
}

Compiled using:
ispc --target avx2-i32x8 -O3 --emit-llvm-text functionispc.ispc -o functionispc.ll

Called supervec using:
$HOME/llvm/build/bin/opt -enable-new-pm=0 -load $HOME/minotaur/build/minotaur.so -so -S functionispc.ll


Sketches output:
$HOME/llvm/build/bin/opt  -enable-new-pm=0 -load $HOME/minotaur/build/minotaur.so -so -S functionispc.ll

PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
