BPF: explicitly specify bpfel triple for certain tests

Commit 54d9f743c8b0 ("BPF: move AbstractMemberAccess and
PreserveDIType passes to EP_EarlyAsPossible") changed most
of CORE tests with opt run followed by llc and opt requires
the target triple specified in the IR.

There are few tests where little endian and big endian will
report different result and for little endian versions of
tests, "target triple = "bpf"" will produce wrong results
if the test executed in a big endian machine, e.g.
PowerPC big endian machine, since target "bpf" represents
host endian and will resolve to "bpfeb".
The builtbot reported such failures when build-and-run
on a PowerPC big endian machine.

To fix the issue, using "target triple = "bpfel"" instead.

[MLIR][OpenMP] Removed the ambiguity in flush op assembly syntax

Bugzilla Ticket No: Bug 46884 []

Flush op assembly syntax was ambiguous:

Consider the below test case:
flush operation is not having any arguments.
But the next statement token i.e "%2" is read as the argument for flush operation and then translator issues an error.
$ cat -n flush.mlir
     1  llvm.func @_QQmain(%arg0: !llvm.i32) {
     2    %0 = llvm.mlir.constant(1 : i64) : !llvm.i64
     3    %1 = llvm.alloca %0 x !llvm.i32 {in_type = i32, name = "a"} : (!llvm.i64) -> !llvm.ptr<i32>
     4    omp.flush
     5    %2 = llvm.load %1 : !llvm.ptr<i32>
     6    llvm.return
     7  }

$ mlir-translate -mlir-to-llvmir flush.mlir
flush.mlir:5:6: error: expected ':'
  %2 = llvm.load %1 : !llvm.ptr<i32>

Introduced begin ( `(` ) and end token ( `)` ) to determince the begin and end of variadic arguments.

The patch includes code changes and testcase modifications.

[OpenMP][FIX] Verify compatible types for declare variant calls

Especially for templates we need to check at some point if the base
function matches the specialization we might call instead. Before this
lead to the replacement of `std::sqrt(int(2))` calls with one that
converts the argument to a `std::complex<int>`, clearly not the desired

[IsKnownNonZero] Handle the case with non-constant phi nodes

Handle the case when all inputs of phi are proven to be non zero.

Constants are checked in beginning of this method before check for depth of recursion,
so it is a partial case of non-constant phi.

Recursion depth is already handled by the function.

[SCEV][NFC] Introduce isBasicBlockEntryGuardedByCond

Currently, we have `isLoopEntryGuardedByCond` method in SCEV, which
checks that some fact is true if we enter the loop. In fact, this is just a
particular case of more general concept `isBasicBlockEntryGuardedByCond`
applied to given loop's header. In fact, the logic if this code is largely
independent on the given loop and only cares code above it.

This patch makes this generalization. Now we can query it for any block,
and `isBasicBlockEntryGuardedByCond` is just a particular case.
