Matheus Almeida a611c0f405 [mips] Add some comments related to the optimization performed in performSELECTCombine.
The structure of the code was slightly modified so that the next patch is easier to read/review.

Matheus Almeida 6b59c449d9 [mips][msa] Fix issue with immediate fields of LD/ST instructions
not being correctly encoded/decoded.
In more detail, immediate fields of LD/ST instructions should be

Tim Northover e4def5e228 ARM: fix yet another stack-folding bug
We were trying to fold the stack adjustment into the wrong instruction in the
situation where the entire basic-block was epilogue code. Really, it can only
ever be valid to do the folding precisely where the "add sp, ..." would be
placed so there's no need for a separate iterator to track that.

Should fix PR18136.

Argyrios Kyrtzidis b9a405b33e [objc] If an interface has no initializer marked as designated and introduces at least one new initializer,
don't assume that it inherits the designated initializers from the super class.

If the assumption was wrong because a new initializer was a designated one that was not marked as such,
we will emit misleading warnings for subclasses of the interface.

Rafael Espindola 117b20c492 Remove the isImplicitlyPrivate argument of getNameWithPrefix.
getSymbolWithGlobalValueBase use is to create a name of a new symbol based
on the name of an existing GV. Assert that and then remove the last call
to pass true to isImplicitlyPrivate.

This gives the mangler API a 1:1 mapping from GV to names, which is what we
need to drop the mangler dependency on the target (and use an extended
datalayout instead).

Faisal Vali 5fb7c3c4ed Fix init-captures for generic lambdas.
For an init capture, process the initialization expression
right away.  For lambda init-captures such as the following:
const int x = 10;
 auto L = [i = x+1](int a) {
   return [j = x+2,
          &k = x](char b) { };
 };
keep in mind that each lambda init-capture has to have:
 - its initialization expression executed in the context
   of the enclosing/parent decl-context.
 - but the variable itself has to be 'injected' into the
   decl-context of its lambda's call-operator (which has
   not yet been created).
Each init-expression is a full-expression that has to get
Sema-analyzed (for capturing etc.) before its lambda's
call-operator's decl-context, scope & scopeinfo are pushed on their
respective stacks.  Thus if any variable is odr-used in the init-capture
it will correctly get captured in the enclosing lambda, if one exists.
The init-variables above are created later once the lambdascope and
call-operators decl-context is pushed onto its respective stack.

Since the lambda init-capture's initializer expression occurs in the
context of the enclosing function or lambda, therefore we can not wait
till a lambda scope has been pushed on before deciding whether the
variable needs to be captured.  We also need to process all
lvalue-to-rvalue conversions and discarded-value conversions,
so that we can avoid capturing certain constant variables.
For e.g.,
 void test() {
  const int x = 10;
  auto L = [&z = x](char a) { <-- don't capture by the current lambda
    return [y = x](int i) { <-- don't capture by enclosing lambda
         return y;
    }
  };
If x was not const, the second use would require 'L' to capture, and
that would be an error.
Make sure TranformLambdaExpr is also aware of this.

David Majnemer 3252fd0d5b Parse: Recover better from bad definitions with base specifiers
We would skip until the next comma, hoping good things whould lie there,
however this would fail when we have such things as this:

struct A {};
template <typename>
struct D;
template <>
struct D<C> : B, A::D;

Once this happens, we would believe that D with a nested namespace
specifier of A was a variable that was being declared. We would go on
to complain that there was an extraneous 'template <>' on their variable
declaration.

Crashes would happen when 'A' gets defined as 'enum class A {}' as
various asserts would fire.

Instead, we should skip up until the semicolon if we see that we are in
the middle of a definition and the current token is a ':'

This fixes PR17084.

Enrico Granata 315133710d Provide an easy way for synthetic child provider front ends to declare themselves “invalid”
This is not being used yet, and in practice, more refactoring would be required to make this fully practical
In practice, the way this should work is that CalculateNumChildren(), GetChildAtIndex(), GetIndexOfChildWithName() and MightHaveChildren() should all default to failure values when m_valid == false. Update() should be the only function actually setting/clearing the flag upon inspecting the backend ValueObject, if it determines it to be in an incongruent state
Given refactoring of the FrontEnd APIs, this work could be automatically performed without the individual providers having to replicate this logic
The way this works now is that each front end picks one or more “key ivars” and keys off those to detect invalidity
This is a baby step 0 to a better world

Summary:
In general, this type node can be used to represent any type adjustment

types without breaking template instantiation.

Mark Lacey d33ff74b19 Simplify the constructor to CodeGenABITypes.
The CodeGenOptions are not used for ABI type selection, so we will just
create one with the default constructor (there is a FloatABI option in
CodeGenOptions that is passed on to LLVM, but not used in Clang for LLVM
IR type generation).

We can use the DiagnosticsEngine on the ASTContext rather than making a
client pass one in explicitly.
