Subject: RFR(M): 8134579: [TESTBUG] Some bmi tests fail if can_access_local_variables is on.
I saw two problems in the intrinsics/bmi/verifycode tests in our nightly runs.
Unfortunately they did not reproduce easily.
With can_access_local_variables() switched on the pattern matched in AddnTestI/L
is messed up with an edge to the Uncommon trap for the NPE.
T/LzcntTestI/L were compiled with an uncommon trap before the call to the
This easily can be fixed by checking for NULL and calling the test function once
Before compiling the method.
I also fixed the name of AddnTestI/L. They actually call TestAndnI/L internally
and thus should be named AndnTestI/L.
Please review this change. I please need a sponsor.
