Remove bad kill flags fom load-and-test.mir as discovered by
https://reviews.llvm.org/D78586: "[MachineVerifier] Add more checks for
registers in live-in lists".
Review: Ulrich Weigand
Summary:
Changing all mnemonic to match assembly instructions to simplify mnemonic
naming rules. This time update all branch instructions. This also change
to use %s10 register consistently.

Add simm7fp/mimmfp to represent floating point immediate values.
Also clean multiclasses to define floating point arithmetic instructions
to handle simm7fp/mimmfp operands. Also add several regression tests
for new operands.

Currently, on PowerPC target, it uses function scope UnsafeFPMath
option to drive Machine Combiner pass.
This is not accurate in two ways:
1: the scope is not accurate. Machine Combiner pass only requires
instruction-level flags instead of the function scope.
2: the float point flag is not accurate. Machine Combiner pass
only requires float point flags reassoc and nsz.

This method has been commented as deprecated for a while. Remove
it and replace all uses with the equivalent getCalledOperand().
I also made a few cleanups in here. For example, to removes use
of getElementType on a pointer when we could just use getFunctionType
from the call.

- Move proposed changes to a separate section to clarify that the
introduction section is not part of the changes.
- Fix formatting typos and add missing reference.
- Clarify why DW_OP_LLVM_offset et al do not wrap on overflow.

Introduce op trait `PolyhedralScope` for ops to define a new scope for
polyhedral optimization / affine dialect purposes, thus generalizing
such scopes beyond FuncOp. Ops to which this trait is attached will
define a new scope for the consideration of SSA values as valid symbols
for the purposes of polyhedral analysis and optimization. Update methods
that check for dim/symbol validity to work based on this trait.

Summary:
In the ppc-expand-isel pass, we use stepForward() to update the
liveins, this function is not recommended, because it needs the
accurate kill info.
This patch uses the function computeAndAddLiveIns() to update the
liveins, it's the recommended method and can fix the liveins bug for
ppc-expand-isel pass..

This is primarily motivated by the desire to move from Python2 to
Python3. `PYTHON_EXECUTABLE` is ambiguous. This explicitly identifies
the python interpreter in use. Since the LLVM build seems to be able to
completed successfully with python3, use that across the build. The old
path aliases `PYTHON_EXECUTABLE` to be treated as Python3.
Fix handling of relocations with r_extern == 0.
If r_extern == 0 then r_symbolnum is an index of a section rather than a symbol index.

We were passing the AppleObjCSection instead of the AddrSection. Maybe
the API changed and this remained unnoticed because the types are the
same, or maybe it's just a typo.
Add llvm.call.preallocated.{setup,arg} instrinsics.
Add "preallocated" operand bundle which takes a token produced by llvm.call.preallocated.setup.
Add "preallocated" parameter attribute, which is like byval but without the copy.
Verifier changes for these IR constructs.

- Adds a folder for integer division by one with the `divi_signed` and `divi_unsigned` ops.
- Creates tests for scalar and tensor versions of these ops.
- Modifies the test in `parallel-loop-collapsing.mlir` so that it doesn't assume division by one will be in the output.

Until recently yaml2obj didn't properly support relocations for MachO.
This behavior resulted in binaries having invalid relocations.
In this diff we adjust the existing tests as follows:
for the tests which don't actually look at any relocations they are removed,
for the tests which essentially depend on relocations they are fixed.

The code assumed that zero-extending the integer constant to the
designated alloc size would be fine even for BE targets, but that's not
the case as that pulls in zeros from the MSB side while we actually
expect the padding zeros to go after the LSB.
I've changed the codepath handling the constant integers to use the
store size for both small(er than u64) and big constants and then add
zero padding right after that.

SmallVector currently uses 32bit integers for size and capacity to reduce
sizeof(SmallVector). This limits the number of elements to UINT32_MAX.
For a SmallVector<char>, this limits the SmallVector size to only 4GB.
Buffering bitcode output uses SmallVector<char>, but needs >4GB output.
This changes SmallVector size and capacity to conditionally use word-size
integers if the element type is small (<4 bytes). For larger elements types,
the vector size can reach ~16GB with 32bit size.
Making this conditional on the element type provides both the smaller
sizeof(SmallVector) for larger types which are unlikely to grow so large,
and supports larger capacities for smaller element types.
This recommit fixes the same template being instantiated twice on platforms
where uintptr_t is the same as uint32_t.
When LIBCLANG_BUILD_STATIC=ON and LLVM_ENABLE_PIC=ON, PIC version of
libclang.a and libclang.so are built as expected. However libclang.a is
not installed. Looking at the macro llvm_add_library(), when both SHARED
and STATIC are set, it renames the static library to ${name}_static and
then adds it to targets. But when add_clang_library() calls install, it
only checks if ${name} is in targets.
To work around this issue, loop through both ${name} and ${name}_static
and install both of them if they're in targets. This is still correct if
only shared or static library is built. In those cases, only ${name} is
added to targets and cmake install will generate the right install
script depending on the library's type.
Test Plan:
cmake with LIBCLANG_BUILD_STATIC=ON and then ninja install, from master
and this diff. Compare the result directory trees. Confirm that only
difference is the added libclang.a.

Summary:
Add logic for emitting the correct set of load commands and segments
when `-dylib` is passed.
I haven't gotten to implementing a real export trie yet, so we can only
emit a single symbol, but it's enough to replace the YAML test files
introduced in D76252.

This patch improves data formatting for CoreFoundation containers:
CFDictionary and CFSet.
These data formatters make the containers and their children appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.
Previous implementation only supported showing the container's element count.
```
(lldb) frame var dict
(__NSCFDictionary *) dict = 0x00000001004062b0 2 key/value pairs
(lldb) frame var set
(__NSCFSet *) set = 0x0000000100406330 2 elements
```
Now the variable can be dereferenced to dispaly the container's children:
```
(lldb) frame var *dict
(__NSCFDictionary) *dict = {
[0] = {
key = 0x0000000100004050 @"123"
value = 0x0000000100004090 @"456"
}
[1] = {
key = 0x0000000100004030 @"abc"
value = 0x0000000100004070 @"def"
}
}
(lldb) frame var *set
(__NSCFSet) *set = {
[0] = 0x0000000100004050 @"123"
[1] = 0x0000000100004030 @"abc"

Defining the nested types `reference` and `iterator_concept` of `reverse_iterator<I>` necessarily requires `I` to be complete in C++20. These tests that verify that `std::map<int, X>::reverse_iterator` can be instantiated when `X` is incomplete are going to have a bad time.

This provides a much cleaner interface into Symbols, and allows for users to start injecting op-specific information. For example, derived op can now inject when a symbol can be discarded if use_empty. This would let us drop unused external functions, which generally have public visibility.
This revision also adds a new `extraTraitClassDeclaration` field to ODS OpInterface to allow for injecting declarations into the trait class that gets attached to the operations.
