Identifier and StringAttr essentially serve the same purpose, i.e. to hold a string value. Keeping these seemingly identical pieces of functionality separate has caused problems in certain situations:
* Identifier has nice accessors that StringAttr doesn't
* Identifier can't be used as an Attribute, meaning strings are often duplicated between Identifier/StringAttr (e.g. in PDL)
The only thing that Identifier has that StringAttr doesn't is support for caching a dialect that is referenced by the string (e.g. dialect.foo). This functionality is added to StringAttr, as this is useful for StringAttr in generally the same ways it was useful for Identifier.

The specific description is [[ https://llvm.discourse.group/t/adding-unsigned-integer-ceil-and-floor-in-std-dialect/4541 | Adding unsigned integer ceil in Std Dialect ]] .
When we lower ceilDivOp this will generate below code, sometimes we know m and n are unsigned intergal.Here are some redundant judgments about positive and negative.
So we need to add some unsigned operations to simplify the instructions.
```
ceilDiv(n, m)
x = (m > 0) ? -1 : 1
return (n*m>0) ? ((n+x) / m) + 1 : - (-n / m)
```
unsigned operations:
```
ceilDivU(n, m)
return n ==0 ? 0 : ((n - 1) / m) + 1
```

The default wchar type on 64-bit AIX is `unsigned int`, so this patch sets `WCHAR_T_TYPE` to `unsigned int` rather than `int`.

BufferizationAliasInfo is used in BufferizationOpInterface::bufferize implementations, so it should be part of the same build target as BufferizableOpInterface.

* Store inplace bufferization decisions in `inplaceBufferized`.
* Remove `InPlaceSpec`. Use a bool instead.
* Use `BufferizableOpInterface::bufferizesToWritableMemory` and `bufferizesToWritableMemory` instead of `getInPlace(BlockArgument)`. The analysis does not care about inplacability of block arguments. It only cares whether the buffer can be written to or not.
* The `kInPlaceResultsAttrName` op attribute is for testing purposes only.
This commit further decouples BufferizationAliasInfo from other dialects such as SCF.

We were previously setting an ignored bit in the kernel headers. The
current behavior is to add the large amount on top of the statically
known size of a single stack frame. I'm not sure if we should just use
the large size as the entire reported size instead.
Previously, our unwind info finalization logic assumed that the LSDA
section referenced by `__compact_unwind` was already finalized before
`__TEXT,__unwind_info` itself. However, that assumption could be broken
by the use of `-rename_section` -- it could be (and is) used to move
`__gcc_except_tab` it into a different segment later in the file.
(__TEXT is always the first non-zerofill segment, so any rename
basically guarantees that the section will be ordered after
`__unwind_info`.)
To handle this case, we compare LSDA relocations instead of their final
values in `UnwindInfoSection::finalize()`, and we actually relocate
those LSDAs in `UnwindInfoSection::writeTo()`. In order to do this, we
need an easy way to track which Symbol a given CUE corresponds to. My
solution was to change our `cuPtrVector` into a vector of indices, with
each index used for both the symbols vector (`symbolsVec`) as well as
the CUE vector (`cuVector`).
This change seems perf neutral. Numbers for linking chromium_framework

Two identical instantiations of a template function can be emitted by two TU's
with linkonce_odr linkage without causing duplicate symbols in linker. MSVC
also requires these symbols be in comdat sections. Linux does not require
the symbols in comdat sections to be merged by linker but by default
clang puts them in comdat sections.
If a template kernel is instantiated identically in two TU's. MSVC requires
that them to be in comdat sections, otherwise MSVC linker will diagnose them as
duplicate symbols. However, currently clang does not put instantiated template
kernels in comdat sections, which causes link error for MSVC.
This patch allows putting instantiated template kernels into comdat sections.

When folding and/or of icmps, look through add of a constant and
adjust the icmp range instead. Effectively, this decomposes
X + C1 < C2 style range checks back into a normal range. This allows
us to fold comparisons involving two range checks or one range check
and some other condition. We had a fold for a really specific case
of this (or of range check and eq, and only one one side!) while
this handles it in fully generality.

`INLNIE_ORIGIN` is simply a string pool for INLINE so that we won't have
duplicated names for inlined functions and can show up anywhere in the symbol

`INLINE` follows immediately after `FUNC` represents the ranges of momery
