8381898: SwitchBootstraps::typeSwitch() not accepting Float, Double types

[dbalek]

With the SwitchBootstraps.typeSwitch(...) method, there is a specification issue (difference between what is written in the method's Javadoc and its actual behaviour) causing some JCK tests to fail.

The proposal here is:
Adjust the Javadoc of the SwitchBootstraps.typeSwitch(...) method to reflect the following changes in the behaviour of the method:

• the method no longer requires a target to be of a reference type (primitive type targets are allowed now)
• primitive type labels are allowed now if the preview features are enabled

---

• I confirm that I make this contribution in accordance with the OpenJDK Interim AI Policy.

Progress

• Change must be properly reviewed (1 review required, with at least 1 Reviewer)
• Change must not contain extraneous whitespace
• Commit message must refer to an issue
• Change requires CSR request JDK-8382163 to be approved
