MIPS64: Remove break_s.
MIPS64: Fix memory grow error when run mjsunit in debug mode.
MIPS64: Fix load SharedFunctionInfo::kCompilerHintsOffset.
MIPS64: Grow builtin code memory size and fix some errors.
MIPS64: add a flag for sim bad address debug to run tests faster.

New flag --sim-dbg-addr, defaults true, which is the default behavior
we have always used. Unaligned addresses or addresses near 0, drop us
into sim debugger.

But by passing --no-sim-dbg-addr to the test runner, we can make
the sim fail fast so these tests do not time out (slowly).

That makes the test suite run a lot faster.
