Fix the bug where merge-fdata unconditionally outputs boltedcollection
line, regardless of whether input files have it set.
Test Plan:
Added bolt/test/X86/merge-fdata-nobat-mode.test which fails without this
fix.
Summary:
This is an essential piece of infrastructure for us to be
continuously testing debug info with BOLT. We can't only make changes
to a test repo because we need to change debuginfo tests to call BOLT,
hence, this diff needs to sit in our opensource repo. But when upstreaming
to LLVM, this should be kept BOLT-only outside of LLVM. When upstreaming,
we need to git diff and check all folders that are being modified by our
commits and discard this one (and leave as an internal diff).
To test BOLT in debuginfo tests, configure it with -DLLVM_TEST_BOLT=ON.
Then run check-lldb and check-debuginfo.

This clarifies that this is an LLVM specific variable and avoids
potential conflicts with other projects.
