Make Blocks depend on BOPS
...
When a BOP is redefined, the BOP redefinition callback will invalidate
any blocks that depend on BOPS. This allows us to eliminate runtime
checks for BOP redefinition.

Also filter with not equal to zero instead of greater than zero, in case

YJIT: Use 2D array to group block versions
...
For deferred compilation, we sometimes want to care about the order of
the block versions. Use an array instead of a linked list to do that.

uJIT: Implement opt_getinlinecache
...
* ujit: implement opt_getinlinecache
Aggressively bet that writes to constants don't happen and invalidate
all opt_getinlinecache blocks on any and all constant writes.
Use alignment padding on block_t to track this assumption. No change to
sizeof(block_t).
* Fix compile warnings when not RUBY_DEBUG
* Fix reversed condition
* Switch to st_table to keep track of assumptions
