javac is generally a short-lived JVM invocation that doesn't greatly
benefit from deep JIT tiering. As such, favor faster startup time
by limiting to tier 1 JIT for javac execution. This should greatly
reduce overall CPU usage from Java compilation for an arbitrary
Android build (~20%), and deliver a small but modest improvement in
overall Java build times (~5%).
Representative incremental build times with this change:
* real 18m3.507s
* user 563m4.838s
and without:
* real 19m11.909s
* user 751m27.790s
Follow-up changes will apply similar flags for other short-lived JVM
build commands.

* changes:
Support building rust modules against musl libc
Support genrules as CrtBegin and CrtEnd in rust
Support multiple crtbegin and crtend dependencies
Add "btf" option that generates BTF debug info to support easier map
inspection. This is accomplished by passing the "-g" flag to clang
when compiling the BPF program.
The "-g" option also generates a number of DWARF debug sections which
are not necessary for loading BTF information, so strip these to avoid
increasing file size unnecessarily. bpfloader currently only supports
BTF info for maps, not programs, so we also strip the .BTF.ext section
containing program BTF info.

Test: libbpf_load_test
Test: verify time_in_state.o includes .BTF section iff "btf: true" is
set
Test: verify time_in_state.o still loads if BTF is enabled

Rust's llvm-project source now includes https://reviews.llvm.org/D97448
and we no longer need this workaround.

present.

This commit adds support for a java_host_test that requires a target
binary to run. If the binary has host and target variants and is added
as a dependency in the `data` attribute, then the host variant is used.
Instead, we need a way to force the use of the target variant.

Currently the list of product variables and whether they are arch-variant is
hard-coded. Instead, we can generate this data from the Soong Product_variables
struct and use soong_injection to consume it in Bazel.

Bug: http://b/216364337
This check warns when return values of standard-library functions
(including fprintf, snprintf) are not checked. Some of these warnings
turn to error when tidy_checks_as_errors in Android.bp.
Disable this for now and follow-up after compiler update to disable or
fix individual instances.

Upcoming versions of the toolchain (at least when I was locally testing)
drop support for the single-dashed argument type. Fixing this ahead of
time as to hopefully avoid the toolchain-release-blocking bug in future
:).

Everything is now switched over to AFDO, let's deprecate sampling PGO.
Keep the code around for a little while longer in case anything needs to
revert back.

Musl will use a genrule output as a linker script in CrtBegin,
support genrules as Crt* dependencies.
