The tests fail to compile there:
```
complex/main.c:4:16: error: expected ';' at end of declaration
  float complex complex_float = -1.5f + -2.5f * I;
               ^
               ;
```

This is a variation of the proposal in D82049 with an extra test.

If neither AT(lma) nor AT>lma_region is specified,
D76995 keeps `lmaOffset` (LMA - VMA) if the previous section is in the
default LMA region.

This patch additionally checks that the two sections are in the same
memory region.

Add a test case derived from https://bugs.llvm.org/show_bug.cgi?id=45313

  .mdata : AT(0xfb01000) { *(.data); } > TCM
  // It is odd to make .bss inherit lmaOffset, because the two sections
  // are in different memory regions.
  .bss : { *(.bss) } > DDR

With this patch, section VMA/LMA match GNU ld. Note, GNU ld supports
out-of-order (w.r.t sh_offset) sections and places .text and .bss in the
same PT_LOAD. We don't have that behavior.

[ELF] Refactor ObjFile<ELFT>::initializeSymbols to enforce the invariant: InputFile::symbols has non null entry

Fixes PR46348.

ObjFile<ELFT>::initializeSymbols contains two symbol iteration loops:

```
for each symbol
  if non-inheriting && non-local
    fill in this->symbols[i]

for each symbol
  if local
    fill in this->symbols[i]
  else
    symbol resolution
```

Symbol resolution can trigger a duplicate symbol error which will call
InputSectionBase::getObjMsg to iterate over InputFile::symbols.  If a
non-local symbol appears after the non-local symbol being resolved
(violating ELF spec), its `this->symbols[i]` entry has not been filled
in, InputSectionBase::getObjMsg will crash due to
`dyn_cast<Defined>(nullptr)`.

To fix the bug, reorganize the two loops to ensure this->symbols is
complete before symbol resolution. This enforces the invariant:
InputFile::symbols has none null entry when InputFile::getSymbols() is called.

```
for each symbol
  if non-inheriting
    fill in this->symbols[i]

for each symbol starting from firstGlobal
  if non-local
    symbol resolution
```

Additionally, move the (non-local symbol in local part of .symtab)
diagnostic from Writer<ELFT>::copyLocalSymbols() to initializeSymbols().

On the buildbot long and int have the same size but long and long long don't,
so the bug where we find the first type by size will produce a different error.
Make the test dynamic based on int/long/long long size to fix the bot.

Lower `shape.shape_of` to standard dialect.
This lowering supports statically and dynamically shaped tensors.
Support for unranked tensors will be added as part of the lowering to `scf`.

The outputs between the direct ast-dump test and the ast-dump test after
deserialization should match modulo a few differences.

For hand-written tests, strip the "<undeserialized declarations>"s and
the "imported"s with sed.

For tests generated with "make-ast-dump-check.sh", regenerate the
output.

Part 1/n.

Some AST dump tests have no "line:" at all. See "ast-dump-wchar.cpp" for
an example.

On AIX, we use __atexit to register dtor functions rather than __cxa_atexit.
So a driver change is needed to default AIX to using -fno-use-cxa-atexit.

Windows platform does not uses __cxa_atexit either. Following its precedent,
we remove the assertion for when -fuse-cxa-atexit is specified by the user,
do not produce a message and silently default to -fno-use-cxa-atexit behavior.

Similar to D81937, we might crash when printing a histogram for a GNU hash table
with a 'symndx' index that is larger than the number of dynamic symbols.

This patch adopts and reuses the `getGnuHashTableChains()` helper which performs
a validation of the table. As a side effect the warning reported for
the --gnu-hash-table was improved.

Also with this change we start to report a warning when the histogram is requested for
the GNU hash table, but the dynamic symbols table is empty (size == 0).

All cases in the test are supported now, it only still failed because an
over-eager regex match not accounting for `, align ` being added to each

Extend the `InheritParentConfig` support introduced in D75184 for the command line option `--config`.
The current behaviour of `--config` is to when set, disable looking for `.clang-tidy` configuration files.
This new behaviour lets you set `InheritParentConfig` to true in the command line to then look for `.clang-tidy` configuration files to be merged with what's been specified on the command line.

Without SSE41 we don't have the PCMPEQQ instruction, making cmp-with-zero reductions more complicated than necessary. We can compare as vXi32 (PCMPEQD) and tweak the MOVMSK comparison to test upper/lower DWORD comparisons.

This pre-fixes something that occurs with null tests for vectors of (64-bit) pointers such as in PR35129.

Summary: It was used inside buildCompilerInvocation to speed up stats. But
preambleStatCache doesn't contain stat information performed while
building compiler invocation. So it was an unnecessary optimization.

Furthermore, buildCompilerInvocation in scanPreamble doesn't need to
find gcc installation, include paths and such, as it is only trying to
lex directives. Hence we are passing an empty FS to get rid of any
redundant IO.
