[SPARK-17792][ML] L-BFGS solver for linear regression does not accept general numeric label column types
## What changes were proposed in this pull request?
Before, we computed `instances` in LinearRegression in two spots, even though they did the same thing. One of them did not cast the label column to `DoubleType`. This patch consolidates the computation and always casts the label column to `DoubleType`.
## How was this patch tested?
Added a unit test to check all solvers. This test failed before this patch.
