[BOLT] Improve BinaryFunction::inferFallThroughCounts() (#105450)
This PR improves how basic block execution count is updated when using
the BOLT option `-infer-fall-throughs`. Previously, if a 0-count
fall-through edge is assigned a positive inferred count N, then the
successor block's execution count will be incremented by N. Since the
successor's execution count is calculated using information besides
inflow sum (such as outflow sum), it likely is already correct, and
incrementing it by an additional N would be wrong. This PR improves how
the successor's execution count is updated by using the max over its
current count and N.

[BOLT][NFC] Add aliases for ICP flags

- `indirect-call-promotion-mispredict-threshold` -> `icp-mp-threshold`

- `indirect-call-promotion-jump-tables-topn` -> `icp-jt-topn`
- `icp-jump-table-targets` -> `icp-jt-targets`
This also fixes an inconsistency in ICP flag names that some start with
`indirect-call-promotion` while others start with `icp`.

[BOLT] Fix profile and tests for nop-removal pass
Summary:
Since nops are now removed in a separate pass, the profile is consumed
on a CFG with nops. If previously a profile was generated without nops,
the offsets in the profile could be different if branches included nops
either as a source or a destination.
This diff adjust offsets to make the profile reading backwards
compatible.

Rebase: [NFC] Refactor sources to be buildable in shared mode
Summary:
Moves source files into separate components, and make explicit
component dependency on each other, so LLVM build system knows how to
build BOLT in BUILD_SHARED_LIBS=ON.
Please use the -c merge.renamelimit=230 git option when rebasing your
work on top of this change.
To achieve this, we create a new library to hold core IR files (most
classes beginning with Binary in their names), a new library to hold
Utils, some command line options shared across both RewriteInstance
and core IR files, a new library called Rewrite to hold most classes
concerned with running top-level functions coordinating the binary
rewriting process, and a new library called Profile to hold classes
dealing with profile reading and writing.
To remove the dependency from BinaryContext into X86-specific classes,
we do some refactoring on the BinaryContext constructor to receive a
reference to the specific backend directly from RewriteInstance. Then,
the dependency on X86 or AArch64-specific classes is transfered to the
Rewrite library. We can't have the Core library depend on targets
because targets depend on Core (which would create a cycle).
Files implementing the entry point of a tool are transferred to the
tools/ folder. All header files are transferred to the include/
folder. The src/ folder was renamed to lib/.
