Remove redundant option -menable-unsafe-fp-math.
There are currently two options that are used to tell the compiler to perform
unsafe floating-point optimizations:
'-ffast-math' and '-funsafe-math-optimizations'.
'-ffast-math' is enabled by default. It automatically enables the driver option
'-menable-unsafe-fp-math'.
Below is a table illustrating the special operations enabled automatically by
'-ffast-math', '-funsafe-math-optimizations' and '-menable-unsafe-fp-math'
respectively.
Special Operations -ffast-math -funsafe-math-optimizations -menable-unsafe-fp-math
MathErrno 0 1 1
FiniteMathOnly 1 0 0
AllowFPReassoc 1 1 1
NoSignedZero 1 1 1
AllowRecip 1 1 1
ApproxFunc 1 1 1
RoundingMath 0 0 0
UnsafeFPMath 1 0 1
FPContract fast on on
'-ffast-math' enables '-fno-math-errno', '-ffinite-math-only',
'-funsafe-math-optimzations' and sets 'FpContract' to 'fast'. The driver option
'-menable-unsafe-fp-math' enables the same special options than
'-funsafe-math-optimizations'. This is redundant.
We propose to remove the driver option '-menable-unsafe-fp-math' and use
instead, the setting of the special operations to set the function attribute
'unsafe-fp-math'. This attribute will be enabled only if those special
operations are enabled and if 'FPContract' is either 'fast' or set to the
default value.

Because the placement of these nodes is critically important (i.e. no

[llvm-profgen] Fix inconsistent loading address issues
This is to fix two issues related with loading address:
1) When multiple MMAPs occur and their loading address are different, before it only used the first MMap as base address, all perf address after it used the wrong base address.
2) For pseudo probe profile, the address is always based on preferred loading address. If the base address is not equal to the preferred loading address, the pseudo probe address query will be wrong.
Solution: Instead of converting the address to offset lazily, right now all the address after parsing are converted on the fly based on preferred loading address in the parsing time. There is no "offset" used in profile generator any more.

[BOLT] Section-handling refactoring/overhaul
Simplify the logic of handling sections in BOLT. This change brings more
direct and predictable mapping of BinarySection instances to sections in
the input and output files.
* Only sections from the input binary will have a non-null SectionRef.
When a new section is created as a copy of the input section,
its SectionRef is reset to null.
* RewriteInstance::getOutputSectionName() is removed as the section name
in the output file is now defined by BinarySection::getOutputName().
* Querying BinaryContext for sections by name uses their original name.
E.g., getUniqueSectionByName(".rodata") will return the original
section even if the new .rodata section was created.
* Input file sections (with relocations applied) are emitted via MC with
".bolt.org" prefix. However, their name in the output binary is
unchanged unless a new section with the same name is created.
* New sections are emitted internally with ".bolt.new" prefix if there's
a name conflict with an input file section. Their original name is
preserved in the output file.
* Section header string table is properly populated with section names
that are actually used. Previously we used to include discarded
section names as well.
* Fix the problem when dynamic relocations were propagated to a new
section with a name that matched a section in the input binary.
E.g., the new .rodata with jump tables had dynamic relocations from
the original .rodata.

[InlineAsm][bugfix] Correct function addressing in inline asm
In Linux PIC model, there are 4 cases about value/label addressing:
Case 1: Function call or Label jmp inside the module.
Case 2: Data access (such as global variable, static variable) inside the module.
Case 3: Function call or Label jmp outside the module.
Case 4: Data access (such as global variable) outside the module.
Due to current llvm inline asm architecture designed to not "recognize" the asm
code, there are quite troubles for us to treat mem addressing differently for
same value/adress used in different instuctions.
For example, in pic model, call a func may in plt way or direclty pc-related,
but lea/mov a function adress may use got.
This patch fix/refine the case 1 and case 2 in inline asm.
Due to currently inline asm didn't support jmp the outsider lable, this patch
mainly focus on fix the function call addressing bugs in inline asm.

[mlir][bufferize] Treat certain aliasing-only uses like memory reads
This fixes an issue in One-Shot Bufferize that could lead to missing buffer copies in the future. This bug can currently not be triggered because of the order in which ops are analyzed (always bottom-to-top). However, if we consider different traversal orders for the analysis in the future, this bug can cause subtle issues that are difficult to debug.
Example:
```
%0 = ...
%1 = tensor.insert ... into %0
%2 = tensor.extract_slice %0
tensor.extract %2[...]
```
In case of a top-to-bottom analysis of the above IR, the `tensor.insert` is analyzed before the `tensor.extract_slice`. In that case, the `tensor.insert` will bufferize in-place because %2 is not yet known to become an alias of %0 (and therefore causing a conflict).
With this change, the `tensor.insert` will bufferize out-of-place, regardless of the traversal order.

Improve dynamic loader support in DynamicLoaderPOSIXDYLD when using core files.
Prior to this fix, no shared libraries would be loaded for a core file, even if they exist on the current machine. The issue was the DYLDRendezvous would read a DYLDRendezvous::Rendezvous from memory of the process in DYLDRendezvous::Resolve() which would read some ld.so structures as they existed in the middle of a process' lifetime. In core files we see, the DYLDRendezvous::Rendezvous::state would be set to eAdd for running processes. When ProcessELFCore.cpp would load the core file, it would call DynamicLoaderPOSIXDYLD::DidAttach(), which would call the above Rendezvous functions. The issue came when during the DidAttach function it call DYLDRendezvous::GetAction() which would return eNoAction if the DYLDRendezvous::m_current.state was read from memory as eAdd. This caused no shared libraries to be loaded for any ELF core files. We now detect if we have a core file and after reading the DYLDRendezvous::m_current.state from memory we set it to eConsistent, which causes DYLDRendezvous::GetAction() to return the correct action of eTakeSnapshot and shared libraries get loaded.
We also improve the DynamicLoaderPOSIXDYLD class to not try and set any breakpoints to catch shared library loads/unloads when we have a core file, which saves a bit of time.

To alleviate the unmanagable footprint growing, this CL introduces the
BatchGroup concept. Each blocks will be classified into a BatchGroup
according to its address. While allocation, we are leaning to allocate
blocks in the same group first. Note that the blocks selected from a

better prediction of dirty page growing speed. Besides, we are able to
