Diana Picus 775bb74379 [ARM GlobalISel] Add tests for PKHBT and PKHTB 
Test (some of) the patterns for selecting PKHBT and PKHTB. The others
are just very similar to the ones we're testing and there would be
little value in covering them as well.

Aleksandar Beserminji 8ee5296152 [mips] Removal of microMIPS64R6 
microMIPS64R6 is removed from backend, and therefore frontend
will show an error when target is microMIPS64R6.

This is Clang part of patch.

Pavel Labath 07d6f881e7 Move PseudoTerminal to the lldb_private namespace 
lldb_utility doesn't make sense, as it is no longer even living in the
"utility" module.

Pavel Labath 390b487994 MainLoop: avoid infinite loop when pty slave gets closed 
Summary:
For ptys (at least on Linux), the end-of-file (closing of the slave FD)
is signalled by the POLLHUP flag. We were ignoring this flag, which
meant that when this happened, we would spin in a loop, continuously
calling poll(2) and not making any progress.

This makes sure we treat POLLHUP as a read event (reading will return
0), and we call the registered callback when it happens. This is the
behavior our clients expect (and is consistent with how select(2)
works).

Craig Topper ad45bf5895 [DAGCombiner] Support folding (mulhs/u X, 0)->0 for vectors.

I need to analyze more carefully. Reverting for now.

Davide Italiano d752d6b4be [DataEncoder] Replace buggy versions of write functions. 
They cause an ubsan error when ran through the testsuite (store
to misaligned address is UB). This commit kills two birds with
one stone, as we also remove some code while fixing it.

Craig Topper a0be5a06c1 [X86] Rename some instructions that start with Int_ to have the _Int at the end. 
This matches AVX512 version and is more consistent overall. And improves our scheduler models.

In some cases this adds _Int to instructions that didn't have any Int_ before. It's a side effect of the adjustments made to some of the multiclasses.
