[Support] Check zstd decompress result before msan unpoison (#117276)
We should check the zstd decompress result before doing the msan
unpoison. If the res is abnormal, then it would be a huge number, which
will cause undesired msan unpoison behavior and will run for a long
time.

Added --offload-compression-level= option to clang and
-compression-level=
option to clang-offload-bundler for controlling compression level.
[HIP] add --offload-compression-level= option (#83605)
Added --offload-compression-level= option to clang and
-compression-level=
option to clang-offload-bundler for controlling compression level.
Added support of long distance matching (LDM) for llvm::zstd which is
off
by default. Enable it for clang-offload-bundler by default since it
improves compression rate in general.
Change default compression level to 3 for zstd for clang-offload-bundler
since it works well for bundle entry size from 1KB to 32MB, which should
cover most of the clang-offload-bundler usage. Users can still specify
compression level by -compression-level= option if necessary.

[Support] Rename llvm::compression::{zlib,zstd}::uncompress to more appropriate decompress
This improves consistency with other places (e.g. llvm::compression::decompress,

Note: when zstd::uncompress was added, we noticed that the API `ZSTD_decompress`
is fine while the zlib API `uncompress` is a misnomer.
