rmcilroy 2e1bdea8ad [Interpreter] Ensure ToBoolean bytecodes are correctly emitted at the start of basic blocks 
Existing code was assuming that 'lexical' blocks were the same as basic
blocks, therefore code which emitted jumps within a lexical block (e.g.,
logical or) would in some occassions incorrectly omit a necessary
ToBoolean.

This change removes Enter/LeaveBlock from BytecodeArrayBuilder and
instead tracks basic blocks via label bindings and jump operations. The
change also ensures we don't emit dead code at the end of a basic block,
and adds tests of the edge cases.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
