[CK] suppress compiler warnings while building pytorch. (#7760) ## Motivation Recently added compiler flags that are required to suppress false warnings by latest staging compiler are not recognized by older compiler versions and are triggering an avalanche of warnings. Previous attempt to suppress them by using -Wno-unknown-warning-option flag didn't help, because that flag wasn't recognized either and just added more warnings. I've verified that current approach by checking the clang version actually works as intended and makes the warnings go away. ## Technical Details <!-- Explain the changes along with any relevant GitHub links. --> ## Test Plan <!-- Explain any relevant testing done to verify this PR. --> ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

/*!
|
|
This class is mainly for being wrapped by EncodedInputStream or AutoUTFInputStream.
|
|
|
|
It is similar to FileReadBuffer but the source is an in-memory buffer instead of a file.
|
|
|
|
Differences between MemoryStream and StringStream:
|
|
1. StringStream has encoding but MemoryStream is a byte stream.
|
|
2. MemoryStream needs size of the source buffer and the buffer don't need to be null terminated.
|
|
StringStream assume null-terminated string as source.
|
|
3. MemoryStream supports Peek4() for encoding detection. StringStream is specified with an
|
|
encoding so it should not have Peek4(). \note implements Stream concept
