[lldb][import-std-module] Do some basic file checks before trying to import a module
Currently when LLDB has enough data in the debug information to import the `std` module,
it will just try to import it. However when debugging libraries where the sources aren't
available anymore, importing the module will generate a confusing diagnostic that
the module couldn't be built.
For the fallback mode (where we retry failed expressions with the loaded module), this
will cause the second expression to fail with a module built error instead of the
actual parsing issue in the user expression.
This patch adds checks that ensures that we at least have any source files in the found
include paths before we try to import the module. This prevents the module from being
loaded in the situation described above which means we don't emit the bogus 'can't
import module' diagnostic and also don't waste any time retrying the expression in the
fallback mode.
For the unit tests I did some refactoring as they now require a VFS with the files in it
and not just the paths. The Python test just builds a binary with a fake C++ module,
then deletes the module before debugging.

[LoopUnswitch] Implement first version of partial unswitching.
This patch applies the idea from D93734 to LoopUnswitch.
It adds support for unswitching on conditions that are only
invariant along certain paths through a loop.
In particular, it targets conditions in the loop header that
depend on values loaded from memory. If either path from
the true or false successor through the loop does not modify
memory, perform partial loop unswitching.
That is, duplicate the instructions feeding the condition in the pre-header.
Then unswitch on the duplicated condition. The condition is now known
in the unswitched version for the 'invariant' path through the original loop.
On caveat of this approach is that one of the loops created can be partially
unswitched again. To avoid this behavior, `llvm.loop.unswitch.partial.disable`
metadata is added to the unswitched loops, to avoid subsequent partial
unswitching.
If that's the approach to go, I can move the code handling the metadata kind
into separate functions.
This increases the cases we unswitch quite a bit in SPEC2006/SPEC2000 &
MultiSource. It also allows us to eliminate a dead loop in SPEC2017's omnetpp

[X86][AMX] Fix tile config register spill issue.
Previous code build the model that tile config register is the user of
each AMX instruction. There is a problem for the tile config register
spill. When across function, the ldtilecfg instruction may be inserted
on each AMX instruction which use tile config register. This cause all
tile data register clobber.
To fix this issue, we remove the model of tile config register. We
analyze the regmask of call instruction and insert ldtilecfg if there is
any tile data register live across the call. Inserting the sttilecfg
before the call is unneccessary, because the tile config doesn't change
and we can just reload the config.
Besides we also need check tile config register interference. Since we
don't model the config register we should check interference from the
ldtilecfg to each tile data register def.
ldtilecfg
/ \
BB1 BB2
/ \
call BB3
/ \
%1=tileload %2=tilezero
We can start from the instruction of each tile def, and backward to
ldtilecfg. If there is any call instruction, and tile data register is
not preserved, we should insert ldtilecfg after the call instruction.

D94954: Fixes Snapdragon Kryo CPU core detection
All of these families were claiming to be a73 based, which was causing
-mcpu/mtune=native to never use the newer features available to these
cores.
Goes through each and bumps the individual cores to their respective Big
counterparts. Since this code path doesn't support big.little detection,
there was already a precedent set with the Qualcomm line to choose the
big cores only.
Adds a comment on each line for the product's name that the part number
refers to. Confirmed on-device and through Linux header naming
convections.
Additionally newer SoCs mix CPU implementer parts from multiple
implementers. Both 0x41 (ARM) and 0x51 (Qualcomm) in the Snapdragon case
This was causing a desync in information where the scan at the start to
find the implementer would mismatch the part scan later on.
Now scan for both implementer and part at the start so these stay in
sync.

Makefile.rules: Avoid redundant .d generation (make restart) and inline archive rule to the only test
Take an example when `CXX_SOURCES` is main.cpp.
main.d is an included file. make will rebuild main.d, re-executes itself [1] to read
in the new main.d file, then rebuild main.o, finally link main.o into a.out.
main.cpp is parsed twice in this process.
This patch merges .d generation into .o generation [2], writes explicit rules
for .c/.m and deletes suffix rules for %.m and %.o. Since a target can be
satisfied by either of .c/.cpp/.m/.mm, we use multiple pattern rules. The
rule with the prerequisite (with VPATH considered) satisfied is used [3].
Since suffix rules are disabled, the implicit rule for archive member targets is
no long available [4]. Rewrite, simplify the archive rule and inline it into the
only test `test/API/functionalities/archives/Makefile`.

[flang] Fix ASSOCIATE statement name resolution
F18 Clause 19.4p9 says:
The associate names of an ASSOCIATE construct have the scope of the
block.
Clause 11.3.1p1 says the ASSOCIATE statement is not itself in the block:
R1102 associate-construct is: associate-stmt block end-associate-stmt
Associate statement associations are currently fully processed from left
to right, incorrectly interposing associating entities earlier in the
list on same-named entities in the host scope.
1 program p
2 logical :: a = .false.
3 real :: b = 9.73
4 associate (b => a, a => b)
5 print*, a, b
6 end associate
7 print*, a, b
8 end
Associating names 'a' and 'b' at line 4 in this code are now both
aliased to logical host entity 'a' at line 2. This happens because the
reference to 'b' in the second association incorrectly resolves 'b' to
the entity in line 4 (already associated to 'a' at line 2), rather than
the 'b' at line 3. With bridge code to process these associations,
f18 output is:
F F
F 9.73
It should be:
9.73 F
F 9.73
To fix this, names in right-hand side selector variables/expressions
must all be resolved before any left-hand side entities are resolved.
This is done by maintaining a stack of lists of associations, rather
than a stack of associations. Each ASSOCIATE statement's list of
assocations is then visited once for right-hand side processing, and
once for left-hand side processing.
Note that other construct associations do not have this problem.
SELECT RANK and SELECT TYPE each have a single assocation, not a list.
Constraint C1113 prohibits the right-hand side of a CHANGE TEAM
association from referencing any left-hand side entity.
