testsuite: Add new tests for early break vectorization.
This adds new test to check for all the early break functionality.
It includes a number of codegen and runtime tests checking the values at
different needles in the array.
They also check the values on different array sizes and peeling positions,
datatypes, VL, ncopies and every other variant I could think of.
Additionally it also contains reduced cases from issues found running over
various codebases.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Also regtested with:
-march=armv8.3-a+sve
-march=armv8.3-a+nosve
-march=armv9-a
