GVN: Enable value forwarding for calloc
Enable value forwarding for loads from `calloc()` without an intervening
store.
This change extends GVN to handle the following case:
%1 = tail call noalias i8* @calloc(i64 1, i64 4)
%2 = bitcast i8* %1 to i32*
; This load is trivially constant zero
%3 = load i32* %2, align 4
This is analogous to the handling for `malloc()` in the same places.
`malloc()` returns `undef`; `calloc()` returns a zero value. Note that
it is correct to return zero even for out of bounds GEPs since the
result of such a GEP would be undefined.

MS ABI: Fix forming pointers to members of a base class
Previously we would calculate the inheritance model of a class when
requiring a pointer to member type of that class to be complete. The
inheritance model is used to figure out how many fields are used by the
member pointer.
However, once we require a pointer to member of a derived class type to
be complete, we can form pointers to members of bases without
calculating the inheritance model for those bases. This was causing
crashes on this simple test case:
struct A {
void f();
void f(int);
};
struct B : public A {};
void g() { void (B::*a)() = &B::f; }
Now we calculate the inheritance models of all base classes when
completing a member pointer type.

mov[fntz] have been replaced by seleqz and selnez. These instructions

mov[fntz].[ds] have been replaced with sel.[ds]
MIPS64r6 currently generates unnecessary sign-extensions for most selects.
This is because the result of a SETCC is currently an i32. Bits 32-63 are
undefined in i32 and the behaviour of seleqz/selnez would otherwise depend
on undefined bits. Later, we will fix this by making the result of SETCC an
i64 on MIPS64 targets.

[mips][mips64r6] madd.[ds], msub.[ds], nmadd.[ds], and nmsub.[ds] are not available on MIPS32r6/MIPS64r6
Summary:
This patch updates both the assembler and the code generator.
MIPS32r6/MIPS64r6 replaces them with maddf.[ds] and msubf.[ds] which are fused
multiply-add/sub operations. We don't emit these yet, this patch only prevents the removed instructions from being emitted.

[mips][mips64r6] Replace m[tf]hi, m[tf]lo, mult, multu, dmult, dmultu, div, ddiv, divu, ddivu for MIPS32r6/MIPS64.
Summary:
The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have
been removed and replaced with GPR-based equivalents. For example:
div $1, $2
mflo $3
is now:
div $3, $1, $2
This patch disables the accumulator-based multiplies and divides for
MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead.
Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the
behaviour of the function.
MipsDelaySlotFiller now invalidates the liveness information when moving
instructions to the delay slot. Without this, divrem.ll will abort since
%GP ends up used before it is defined.

Do not use namespace polly inside a header.
In general this fixes ambiguity that can arise from using
a different namespace that declares the same symbols as
we do.
One example inside llvm would be:
createIndVarSimplifyPass(..);

llvm/Transforms/Scalar.h

Check for an empty error log.
Fixes #19976.
The error log does not contain an error, in case we reject a candidate
without generating a diagnostic message by using invalid<>(...). This is
the case for the top-level region of a function.
The patch comes without a test-case because adding a useful one requires
additional code just for triggering it. Before the patch it would only trigger,
if we try to print the CFG with Scop error annotations.
