This patch is the first step to enable support of GNU attribute in LLVM
PowerPC, enabling it for PowerPC targets, otherwise llvm-mc raises error
when seeing the attribute section.

Pulled out of D106237, this folds truncstore(extend(x)) back to store(x)
if the original store was legal. This can come up due to the order we
fold nodes. A fold from X86 needs to be adjusted to prevent infinite
loops, to have it pick the operand of a trunc more directly.

This reapply `de872382951572b70dfaefe8d77eb98d15586115`, which was
reverted in `fdb6578514dd3799ad23c8bbb7699577c0fb414d`
Add `# REQUIRES: asserts` in test file `anonymous_symbol.s` to disable
this test for non-debug build
Fixes the build issue with D111034, whose goal was to optimize
add/sub with long immediates.
Optimize ([add|sub] r, imm) -> ([ADD|SUB] ([ADD|SUB] r, #imm0, lsl #12), #imm1),
if imm == (imm0<<12)+imm1. and both imm0 and imm1 are non-zero 12-bit unsigned
integers.
Optimize ([add|sub] r, imm) -> ([SUB|ADD] ([SUB|ADD] r, #imm0, lsl #12), #imm1),
if imm == -(imm0<<12)-imm1, and both imm0 and imm1 are non-zero 12-bit unsigned
integers.
The change which fixed the build issue in D111034 was the use of new virtual
registers so that SSA form is maintained until deleting MI.

Allow users to create aliases for aliases to raw input commands. That probably
sounds convoluted, so here's an example:
```
command alias some-setup env SOMEVAR=SOMEVALUE
```
This an alias based on `env`, which itself is an alias for `_regex-env`.
`_regex-env` is a `command regex` command, which takes raw input.
The above `some-setup` alias fails with:
```
error: Unable to create requested alias.
```
This change allows such aliases to be created. lldb already supports aliases to
aliases for parsed commands.

User-defined derived type I/O implementation subroutines and

`_vfork` moved from libsystem_kernel.dylib to libsystem_c.dylib as part
of the below changes. The iOS simulator does not actually have
libsystem_kernel.dylib of its own, it only has the host Mac's. The
umbrella-nature of Libsystem makes this movement transparent to
everyone; except the simulator! So when we "back deploy", i.e., use the
current version of TSan with an older simulator runtime then this symbol
is now missing, when we run on the latest OS (but an older simulator
runtime).
Note we use `SANITIZER_IOS` because usage of vfork is forbidden on iOS
and the API is completely unavailable on watchOS and tvOS, even if this
problem is specific to the iOS simulator.
Caused by:

User-defined derived type editing in formatted I/O wasn't
working with repeat counts; e.g., "2DT(10)". The solution required
some code to be moved from GetNextDataEdit() to CueUpNextDataEdit() so
that a stack entry for a nonparenthesized repeated data edit
descriptor would work correctly -- all other data edit descriptors
are capable of dealing with repetition in their callees, so the bug
hadn't been exposed before.
Debugging this problem led to some improvements in error messages
for bad format strings, and those changes have been retained; also,
a dead member function was discovered and expunged.

This change adds support for split-file to respect the line ending style
of the input file. This enables split-file to work as expected on
Windows with input files containing CRLF line endings.
The test files added along with this change mirror the existing basic
tests, but are forced to contain CRLF line endings via git attributes.
This will result in the tests always containing CRLF line endings when
checked out regardless of the user's OS.

Looks like e9211e0393 unfortunately broke the sanitizer build bots,
because those bots compile the symbolizer with DLLVM_ENABLE_THREADS=Off.
Likely, before the patch, this header was transitively included.
Rationale:
Although file I/O is a bit alien to MLIR itself, we provide two convenient ways
for sparse tensor I/O. The input part was already there (behind the swiss army
knife sparse_tensor.new). Now we have a sparse_tensor.out to write out data. As
before, the ops are kept vague and may change in the future. For now this
allows us to compare TACO vs MLIR very easily.

I'm seeing deprecated warnings due to using mallinfo() instead of
mallinfo2().
../../llvm/lib/Support/Unix/Process.inc:98:10: warning: 'mallinfo' is deprecated [-Wdeprecated-declarations]
mi = ::mallinfo();
mallinfo2() is part of glibc 2.33 which was released in Feb 2021, which
is fairly recent but I think gn users should be using fairly up to date
glibcs.
If this breaks people we could make this a gn arg instead.

Add support for Swift reflection metadata to dsymutil.
This patch adds support for copying Swift reflection metadata (__swift5_.* sections) from .o files to into the symbol-rich binary in the output .dSYM. The functionality is automatically enabled only if a .o file has reflection metadata sections and the binary doesn't. When copying dsymutil moves the section from the __TEXT segment to the __DWARF segment.
