Fixed 6896381: CTW fails share/vm/ci/bcEscapeAnalyzer.cpp:99, assert(_stack_height < _max_stack,"stack overflow")
Bytecode Analyzer emulates stack usage to track
objects reference. For constants load (ldc) it
loads a constant from constant pool to check its
type but it does not check T_ILLEGAL type returned
for unloaded strings and klasses when no space left
Check constant Tag type instead since we need
to know only constant's type.
Also changed asserts to guarantee to avoid memory
stomp in product VM.
Tested with CTW.
