Francis Visoiu Mistrih 726c342ce2 [macho][NFC] Extract all CPU_(SUB_)TYPE logic to libObject
This moves all the logic of converting LLVM Triples to
MachO::CPU_(SUB_)TYPE from the specific target (Target)AsmBackend to
more convenient functions in libObject.

This also gets rid of the separate two X86AsmBackend classes.

Jordan Rupprecht 0ffa6e1a7e [lldb] Fix version string when using LLDB_REVISION but not LLDB_REPOSITORY
Summary:
lldb's format string (line one) is:
`lldb version $clang_version ($lldb_repo revision $lldb_revision)`

When only using $lldb_revision and not $lldb_repo, this might look like:
`lldb version 11 ( revision 12345)`
which looks pretty ugly.

Aside: I'm not sure we really need all the different versions since we've moved to the monorepo layout -- I don't think anyone is using different llvm/clang/lldb revisions, are they? We could likely tidy this up further if we knew how people consumed the output of lldb --version.

Craig Topper 3543ac9ab5 [X86] Rewrite LowerBRCOND to remove dead code and handle ISD::SETCC and overflow ops directly.
There's a lot of old leftover code in LowerBRCOND. Especially
the detecting or AND or OR of X86ISD::SETCC nodes. Those were
needed before LegalizeDAG was changed to visit nodes before
their operands.

It also relied on reversing the output of LowerSETCC to find the
flags producing node to use for the X86ISD::BRCOND node.

Rather than using LowerSETCC this patch uses emitFlagsForSetcc to
handle the integer ISD::SETCC case. This gives the flag producer
and the comparison code to use directly. I've removed the addTest
flag and just produce a X86ISD::BRCOND and return immediately.

Floating point ISD::SETCC case is just an X86ISD::FCMP with special
care for OEQ and UNE derived from the previous code. I've left
f128 out so it will emit a test. And LowerSETCC will be called
later to produce a libcall and X86ISD::SETCC. We have combines
that can merge the test and X86ISD::SETCC.

We need to handle two cases for overflow ops. Either they are used
directly or they have a seteq 0 or setne 1 to invert the overflow.
The old code did not handle the setne 1 case, but I think some
other combines were making up for it.

If we fail to find a condition, we'll wrap an AND with 1 on the
original condition and tell emitFlagsForSetcc to emit a compare
with 0. This will pickup the LowerAndToBT and or the EmitTest case.
I kept the isTruncWithZeroHighBitsInput call, but we might be able
to fold that in to emitFlagsForSetcc.

Sanjay Patel 15e20dcb8f [Utils][x86] add an option to reduce scrubbing of shuffles with memops
I was drafting a patch that would increase broadcast load usage,
but our shuffle scrubbing makes it impossible to see if the memory
operand offset was getting created correctly. I'm proposing to make
that an option (defaulted to 'off' for now to reduce regression
test churn).

The updated files provide examples of tests where we can now verify
that the pointer offset for a loaded memory operand is correct. We
still have stack and constant scrubbing that can obscure the operand
even if we don't scrub the entire instruction.

[Sema] Demote call-site-based 'alignment is a power of two' check for AllocAlignAttr into a warning
Summary:
As @rsmith notes in https://reviews.llvm.org/D73020#inline-672219
while that is certainly UB land, it may not be actually reachable at runtime, e.g.:
```
template<int N> void *make() {
  if ((N & (N-1)) == 0)
    return operator new(N, std::align_val_t(N));
  else
    return operator new(N);
}
void *p = make<7>();
```
and we shouldn't really error-out there.

That being said, i'm not really following the logic here.
Which ones of these cases should remain being an error?

Raphael Isemann fdea9a4ec9 [lldb] Remove license headers from all test source files
Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.

The reasons for this are:

* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.

For the record, the following tests had their line numbers changed to pass with the removal of the license header:
    lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
    lldb-shell :: Reproducer/TestGDBRemoteRepro.test
