Subject: [PATCH] Updated index.md to add a command which can show unoptimized
 MIR

The current playground link used in the page of MIR shows a optimized version of MIR which is missing some statements such as StorageLive . Updated to use a local command which shows unoptimized MIR that would be more useful for pedagogical purposes.

+MIR shown by above link is optimized.
+Some statements like `StorageLive` are removed in optimization.
+This happens because compiler notices the value is never acessed in the code.
+We can use `rustc [filename].rs -Z mir-opt-level=0 --emit mir` to view unoptimized MIR.
+This requires the nightly toolchain.
