llvm-symbolizer: Don't crash when referencing an invalid CU in a dwp file twice

[flang] Avoid ICE in case of subprogram name clash with runtime namespace.

This is related to llvm-project#61074.
In general, it is undefined behavior if user subprogram is declared
with a name that matches a name of function from any runtime library
that Flang is using (e.g. FortranRuntime, libm, etc.). With this change-set
we avoid ICE for invalid calls generated during math lowering by
type casing the function before the call. This happens when a user function
call is lowered before the math function call with the same name.
To detect the name clash in cases when the math function call is lowered
before the user function call we set fir.runtime attribute for the math
functions and check it when we lower the user function call.

The warnings are currently emitted only in debug compiler and
under llvm debug options. I think they should be reported
in the same way as regular Flang warnings.

Note that this change-set does not resolve issues with the conversion
passes that might introduce libm calls after the lowering.

[SCEV] Apply loop guards against min/max for its arguments

This replaces several rewriting rules in ScalarEvolution::applyLoopGuards
that are applied to min/max expressions with the equivalent ones but
applied to its arguments.
So previously given we had a loop guard min(a, b) >= c,
the min expression would get rewritten as max(c, min(a, b)).
With such approach, we were unable to apply the rewrite if min operands
were zext for example (min(zext(a), zext(b))), however it's equivalent
to the expression zext(min(a, b)) for which we could apply the rewrite.

Now we'd rewrite the min operands also with these expressions:
a -> max(c, a) and
b -> max(c, b).
and this would allow us to apply the loop guard in this and similar cases:
min(zext(a), zext(b)) would get rewritten as min(zext(max(c, a)), zext(max(c, b)))
instead of just being skipped.

The list of added rules (omitting predicates signedness for simplicity):
1. Guard:     min(a, b) >= c
   Old rule:  min(a, b) -> max(c, min(a, b))
   New rules: a -> max(a, c) and b -> max(b, c)
2. Guard:     min(a, b) > c
   Old rule:  min(a, b) -> max(c + 1, min(a, b))
   New rules: a -> max(a, c + 1) and b -> max(b, c + 1)
3. Guard:     max(a, b) <= c

   New rules: a -> min(a, c) and b -> min(b, c)
4. Guard:     max(a, b) < c

The following is the part of BTF generation sequence:
  (1). 'struct t2 *arg' -> 'struct t1 *p1'
       In this step, the type 'struct t1' will be generated as
       a forward decl and the ptr type (to 'struct t1') will
       be stored in the internal type table.
  (2). now the second field 'struct t1 *p2' will be processed.
       Since the ptr type (to 'struct t1') already in the type
       table, the existing logic strips out ptr modifier and
       is able to generate BTF type for 'struct t1'.

In the above step (2), if CheckPointer is true (the type traversal
chain including a struct member), 'ptr' modifier should be checked
and the subsequent type generation should be skipped since
the same case has been processed in visitDerivedType().

The issue is exposed when I am trying to use llvm15 to compile
some internal bpf programs. The bpf skeleton put the whole
ELF section (after striping some sections like dwarf) as a string.
The large BTF section triggered the following error:

  bpf_object_with_struct_ops_test_prog_bpf/BpfObjectWithStructOpsTestProg.skel.h:222:23:
  error: string literal of length 140144 exceeds maximum length 65536 that C++ compilers
  are required to support [-Werror,-Woverlength-strings]
        return (const void *)"\
                             ^~
  1 error generated.

Although adding -Wno-overlength-strings could workaround the issue,
improving llvm BTF generation sounds better esp. for users using vmlinux.h.

MSVC: support version preference with search

Extend the logic for the WinSDK and UCRT handling to prefer a user
specified version of the VisualC++ tools and Windows SDK.  This allows
us to now perform the regular search for the installation but select the
exact version of the SDK or VC++ tools to override the latest version.
Similar to the other flags controlling this behaviour, if the user
specifies a value, we will not perform validation on the input and will
attempt to prefer that, particularly in the case of VisualC++ tools
where no fallback occurs.
