another one for distributed mode.
Currently during module importing, ThinLTO opens all the source modules,
collect functions to be imported and append them to the destination module,
then leave all the modules open through out the lto backend pipeline. This
patch refactors it in the way that one source module will be closed before
another source module is opened. All the source modules will be closed after
importing phase is done. It will save some amount of memory when there are
many source modules to be imported.
Note that this patch only changes the distributed thinlto mode. For in
process thinlto mode, one source module is shared acorss different thinlto
backend threads so it is not changed in this patch.

See PR45088.
Compound requirement type constraints were using decltype(E) instead of
decltype((E)), as per `[expr.prim.req]p1.3.3`.
Since neither instantiation nor type dependence should matter for
the constraints, this uses an approach where a `decltype` type is not built,
and just the canonical type of the expression after template instantiation
is used on the requirement.

`allocClassWithName` allocates an object with the given type.
The type is actually provided as a string argument (type's name).
This creates a possibility for not particularly useful warnings
from the analyzer.
In order to combat with those, this patch checks for casts of the
`allocClassWithName` results to types mentioned directly as its
argument. All other uses of this method should be reasoned about
as before.

It makes sense to track rvalue expressions in the case of special
concrete integer values. The most notable special value is zero (later
we may find other values). By tracking the origin of 0, we can provide a
better explanation for users e.g. in case of division by 0 warnings.
When the divisor is a product of a multiplication then now we can show
which operand (or both) was (were) zero and why.

In JavaScript, `- -1;` is legal syntax, the language allows unary minus.
However the two tokens must not collapse together: `--1` is prefix
decrement, i.e. different syntax.
Before:
- -1; ==> --1;
After:
- -1; ==> - -1;
This change makes no attempt to format this "nicely", given by all
likelihood this represents a programming mistake by the user, or odd
generated code.
The check is not guarded by language: this appears to be a problem in
Java as well, and will also be beneficial when formatting syntactically
incorrect C++ (e.g. during editing).

Since the introduction of class properties in Objective-C it is possible to declare a class and an instance
property with the same identifier in an interface/protocol.
Right now Clang just generates debug information for whatever property comes first in the source file.
The second property is ignored as it's filtered out by the set of already emitted properties (which is just
using the identifier of the property to check for equivalence). I don't think generating debug info in this case
was never supported as the identifier filter is in place since 7123bca7fb
(which precedes the introduction of class properties).
This patch expands the filter to take in account identifier + whether the property is class/instance. This
ensures that both properties are emitted in this special situation.

After c773d0f973 the remark is only emitted if the loop is profitable
to vectorize, but cannot be vectorized. Hence, it depends on
X86-specific cost-modeling.
The original issue is caused by the fact that the variable is allocated
with incorrect type i1 instead of i8. This causes the bitcasting of the
declaration to i8 type and the bitcast expression does not match the
original variable.
To fix the problem, the UndefValue initializer and the original
variable should be emitted with type i8, not i1.

We should have a test verifying / \ for Windows but have such a long

Currently we want to allow calling non-const methods even when only a
shared lock is held, because -Wthread-safety-reference is already quite
sensitive and not all code is const-correct. Even if it is, this might
require users to add std::as_const around the implicit object argument.

The contents of the string returned by getenv() is not guaranteed across calls to getenv(). The code to handle the CC_PRINT etc env vars calls getenv() and saves the results in just a char *. The string returned by getenv() needs to be copied and saved. Switching the type of the strings from char * to std::string will do this and manage the alloated memory.

IR values convert to check prefix FileCheck variables for IR checks. For example, nameless values, e.g., %0, convert to check prefix TMP FileCheck variables, e.g., [[TMP0:%.*]]. This check prefix may clash with named values that have the same name and that causes auto-generated tests to fail. Currently a warning is emitted to change the names of the IR values but this is not always possible, if for example they are generated by clang. Manual intervention to fix the FileCheck variable names is too tedious. This patch add a parameter to prefix conflicting FileCheck variable names with a user-provided string to automate the process.
