  -----------
  [AArch64] NFC: Make some AArch64-SVE LoopVectorize tests generic.

This change moves most of `sve-inductions.ll` to non-AArch64 specific
LV tests using the `-target-supports-scalable-vectors` flag, because they're
not explicitly AArch64-specific. One test builds on AArch64-specific
knowledge regarding masked loads/stores, and remains in sve-inductions.ll.

  Log Message:
  -----------
  [LV] Don't let ForceTargetInstructionCost override Invalid cost.

Invalid costs can be used to avoid vectorization with a given VF, which is
used for scalable vectors to avoid things that the code-generator cannot
handle. If we override the cost using the -force-target-instruction-cost
option of the LV, we would override this mechanism, rendering the flag useless.

This change ensures the cost is only overriden when the original cost that
was calculated is valid. That allows the flag to be used in combination
with the -scalable-vectorization option.
