Avoid multiple nops before payload instructions

From b/78072750 it was discovered that some versions of Art had issues
with multiple simple nops before a payload instruction.

This could happen, as both the initial dex code generation and the subsequent
jumbo string rewriting (after distribution to dex files) could insert a nop
before a payload instruction to ensure the required alignment.

The jumbo string rewriting now removes a nop if possible to ensure alignment.
