Switch lowering: enable whole-switch jump tables at -O0. To same compile time, the analysis to find dense case-clusters in switches is not done at -O0. However, when the whole switch is dense enough, it is easy to turn it into a jump table, resulting in much faster code with no extra effort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240071 91177308-0d34-0410-b5e6-96231b3b80d8
