JDK-8271556: [lworld] java.lang.BootstrapMethodError in .equals() for primitive record

[mlchung]

We want the default choice is to use the primary L-type mirror and only
when there is a contextual need to make a distinction, the Q-type mirror will be an option.

The proposal is to always pass the primary mirror to the recordClass argument
and adjust the bootstrap code to drive method handle creation off of the primitive
value type of the record class instead of recordClass, using recordClass only
for getting the class name for toString.

The patch also works here. Just a minor stylistic suggestion where a pattern could save a few casts.

[jespersm]

Nitpicking: Perhaps

if (type instanceof MethodType mType) {
    methodType = mType;
    if (mType.parameterType(0) != receiverType) {

?

[mlchung]

sure. I may fix it in jdk repo directly.
