[X86] Add AMD Matisse (znver2) model number to getHostCPUName and
compiler-rt's getAMDProcessorTypeAndSubtype.
This is the CPUID model used on Ryzen 3000 series (Zen 2/Matisse) CPUs.

[ThinLTO] Promotion handling cleanup (NFC)
Summary: Clean up the code that does GV promotion in the ThinLTO
backends.
Specifically, we don't need to check whether we are importing since that
is already checked and handled correctly in shouldPromoteLocalToGlobal.
Simply call shouldPromoteLocalToGlobal, and if it returns true we are
guaranteed that we are promoting, whether or not we are importing (or in
the exporting module). This also makes the handling in getName()
consistent with that in getLinkage(), which checks the DoPromote
parameter regardless of whether we are importing or exporting.

Update the docs for building libc++.
Summary: Rewrite the in-tree build to be a clearer tl;dr like we have
for the out-of-tree build.

[Sema] Fix a -Wobjc-signed-char-bool false-positive
Unsigned bit-field flags can only have boolean values, so handle that
case in Expr::isKnownToHaveBooleanValue.
