Revert^2 "x86_64: Add JIT support for LoadMethodType."

This reverts commit 69c9ea4f93a688ff50e08060be37bcfd3f3e9910.

Instead of storing reversed method_code_map_, now just keep
MethodType-s associated with a compiled code.
Increasing constant in 979/Main.java to trigger jit more reliably.

Bug: 297147201

Test: CtsPerfettoTestCases
Test: ./art/test/testrunner/testrunner.py --host --64 --jit -b
Test: ./art/test/testrunner/testrunner.py --host --64 -b
Test: ./art/test.py --host -b
