  3. Fix LLVM test to use %python instead of python 

    This uses lit substitution, which fixes running this test on
some environment where 'python' isn't in the path.

  4. [DA] Remove special handling for SCEVAddExpr in GCD MIV (llvm#169927) 

    In `gcdMIVtest`, there is logic that assumes the addition(s) of
`SCEVAddExpr` don't overflow without any checks. Adding overflow checks
would be fine, but this part appeart to be less useful. So this patch
removes it.

Fix one of the tests added in llvm#169926.

  6. [CIR] Start printing/parsing func 'attributes' (llvm#169674) 

    This patch adds a print and parse ability for the func to have
MLIR-standard 'attributes' printed along side the standard function.

This patch also seeds the initial "disallowed" list so that we don't
print things that we have custom printing for, AND will disallow them
from being parsed. I believe this list to be complete, and it passes all
tests.

This printing of attributes is necessary for testing some OpenACC things
that putting into the normal func-printing seems unnecessary.

  7. [AggressiveInstCombine] Fix memory location for alias analysis (llvm#… 

    …169953)

When LOps.RootInsert comes after LI2, since we use LI2 as the new insert
point, we should make sure the memory region accessed by LOps isn't
modified. However, the original implementation passes the bit width
`LOps.LoadSize` as the number of bytes to be accessed, causing BasicAA
to return NoAlias:

https://github.com/llvm/llvm-project/blob/a941e150749650e6a75e948f10d46b0bedcc128b/llvm/lib/Analysis/BasicAliasAnalysis.cpp#L1658-L1667
With `-aa-trace`, we get:
```
End ptr getelementptr inbounds nuw (i8, ptr @g, i64 4) @ LocationSize::precise(1),   %gep1 = getelementptr i8, ptr %p, i64 4 @ LocationSize::precise(32) = NoAlias
```
This patch uses `getTypeStoreSize` to compute the correct access size
for LOps. Instead of modifying the MemoryLocation for End (i.e.,
`LOps.RootInsert`), it also uses the computed base and AATag for
correctness.

Closes llvm#169921.

    …lvm#170145)

This is a tiny change that would make the function contract more clear
and our work downstream easier.

  9. [lldb-dap] Fix segfault in JSONUtils.cpp when GetUUIDString() returns… 

    … nullptr (llvm#169844)

When creating a stack frame in JSONUtils.cpp CreateStackFrame() the code
constructs a std::string from module.GetUUIDString(), which can return
nullptr in some cases (as documented in the implementation of
SBModule::GetUUIDString()). This causes a segmentation fault when passed
to the std::string constructor.

This fix adds a null check before constructing the UUID string, falling
back to an empty string if nullptr is returned. The existing empty check
ensures the moduleId field is omitted from the JSON when no UUID exists.

  10. [llvm-exegesis] Add CLI Option to set Fixed RNG seed 

    The primary motivation for this is to set a fixed RNG seed for flaky
tests. This also has the bonus of adding debug logging for what seed
gets used which can make it much easier to reproduce issues that only
happen occasionally and are seed-dependent.

    …lvm#168990)

There's `arrayType` matcher for matching `ArrayType`, but no matcher for
`ArrayTypeLoc`. This change complements it.

Note that there's already `hasElementTypeLoc` matcher, which was
declared together with the `hasElementType` matcher.
