Reapply "[MemProf] Use radix tree for alloc contexts in bitcode summaries" (#117395) (#117404)
This reverts commit fdb050a5024320ec29d2edf3f2bc686c3a84abaa, and
restores ccb4702038900d82d1041ff610788740f5cef723, with a fix for build
bot failures.
Specifically, add ProfileData to the dependences of the BitWriter
library, which was causing shared library builds of LLVM to fail.
Reproduced the failure with a shared library build and confirmed this
change fixes that build failure.

[MemProf] Use radix tree for alloc contexts in bitcode summaries (#117066)
Leverage the support added to represent allocation contexts in a more
compact way via a radix tree in the indexed profile
[MemProf] Use radix tree for alloc contexts in bitcode summaries (#117066)
Leverage the support added to represent allocation contexts in a more
compact way via a radix tree in the indexed profile to similarly reduce
sizes of the bitcode summaries.
For a large target, this reduced the size of the per-module summaries by
about 18% and in the distributed combined index files by 28%.
