Generating PDB files on Windows
1. Add /Z7 as compiler flag in CROSSTOOL, this causes full debugging
infomation built into object files, no PDB file is generated.
2. Add /DEBUG as linker flag so that a PDB file will be generated for
executable or dll.
* /DEBUG:FULL for dbg mode. the full PDB can be used to debug the
executable when no other build products are available, such as
when the executable is deployed.
* /DEBUG:FASTLINK for fastbuild mode. object files are still needed
when debugging the executable, but linking speed can be two to four
times faster that full PDB generation.
* No option is added for opt mode.

3. Add an empty feature in MSVC CROSSTOOL to tell Bazel we need PDB file
4. Add PDB file artifact in an output named pdb_file of cc_binary,
then you can build the pdb file by bazel build //foo/bar:bin --output_groups=pdb_file
5. Add test for PDB file generation

{Fast, Correct} - Choose two
Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:
A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.
An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.
Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
