SubElementInterfaces forbids all mutable types and attributes from
implementing `replaceImmediateSubElements`. However, this prohibits
literal structs, which are immutable, from implementing that function.
This patch defers the decision on whether to support
`replaceImmediateSubElements` to the individual types/attributes.

Differential Revision: https://reviews.llvm.org/D136029

This moves the `LLVMArrayType` to a `TypeDef`. The main side-effect of
this change is that the syntax `array<4xi32>` is no longer allowed. It
was previously parsed and then printed as `array<4 x i32>`. Now the
syntax must be the latter.

This adds a '--no-implicit-module' option, which disables the insertion
of a top-level 'builtin.module' during parsing.

The translation APIs are also updated to take/return 'Operation*'
instead of 'ModuleOp', to allow other operation types to be used. To
simplify translations which are restricted to specific operation types,
'TranslateFromMLIRRegistration' has an overload which performs the
necessary cast and error checking.

This reverts commit 8d89dbce since
this broke the compiler-rt build.

flang/test/Semantics/test_errors,py only compares actual error messages
with expected error messages.  Many tests have expected warning messages
in them, but they are not checked.

A forthcoming change adds several new warning and explanatory messages
to the compiler, and these messages must be testable.

So (re-?) enable non-error message checking in test_errors.py and adjust some
existing tests to get them to pass.

Warning messages related to host-specific folding conditions will not
be emitted on all platforms, so they will continue to be ignored.

updated a few test running multiple passes.

The logical view is traversed and for each logical element a
series of match criterias are applied. One of those criterias
is to match its name or type name to a given pattern.

If the logical element does not have a type (for instance a
'namespace') do not try to use its type name, which is a
empty string as the 'matcher' function receives a null pointer.

1. When we evaluating an expression multiple times and the searching scope is translation unit, ParseDeclsForContext iterates the type info and symbol info multiple times, though only the debug info is parsed once. Using llvm::call_once to make it only iterating and parsing once.

2. When evaluating an expression with identifier whose parent scope is a namespace, ParseDeclsForContext needs to search the entire type info to complete those records whose name is prefixed with the namespace's name and the entire symbol info to to parse functions and non-local variables. Caching parsed namespaces to avoid unnecessary searching.

Mixing GCC and Clang object files in this case is not ideal. .bss._ZGVN1BIiE1aE
has different COMDAT groups. It appears to work in practice because the guard
variable prevents harm due to double initialization.

For the linker, we just stick with the rule that a weak binding does not cause
"duplicate symbol" errors.
