Add a user-specifiable vscale_range that is recorded on the executable target. This will be used for lowering later on, specifically while setting tile sizes and aligning them to scalable vector sizes. For targets that support scalable vectorization, specifying this flag is a requirement if scalable vectorization is also enabled. If the target has +zvl*b features and the user specifies a lower bound, the maximum of the two lower bounds will be effective. Signed-off-by: Ege Beysel <beyselege@gmail.com>

In-lieu of the feedback on #24698, this PR adds a user-specifiable
vscale_rangethat is recorded on the executable target and that also stamps the dispatches. This will be used for lowering later on, specifically while setting tile sizes and aligning them to scalable vector sizes.For targets that support scalable vectorization, specifying this flag is a requirement if scalable vectorization is also enabled. If the target has
+zvl*bfeatures and the user specifies a lower bound, the maximum of the two lower bounds will be effective.Assisted-by: Claude Code
