RFR: 8216275: Disable annotation processing lint warnings when building microbenchmarks

[Claes Redestad]

Hi,

current use of -Xlint makes the build-microbenchmark fail if one 
attempts to add a microbenchmark that uses non-JMH annotations.

Patch selectively disable the processing lint option without disabling
other linters.
