RFR: 8282509: [AIX] ResolvedTestClass fails on AIX with similar output

[Tyler Steele]

This is a tentative solution to a failure observed on AIX. The solution is tentative because I require help to ensure that something deeper and more problematic is not happening.

The test fails because the output produced by PrintCompilation produces `LambdaForm$MH/0x00000007c0002400` instead of `Invokers$Holder` as it does on other platforms. There is one other place the output is different, when `DirectMethodHandle$Holder` is replaced with `LambdaForm$DMH/0x00000007c0001c00`. Ignoring these name changes, the output of PrintCompilation is identical. I observe the same compilations (including the OSR/non-OSR, and same level) in the same order.

I would be grateful for help understanding the root of the difference behind the change. I have a few ideas, but I will let you build your own interpretations free from my potentially incorrect understanding (i.e. no spoilers). Thanks in advance.
