Seems like MSVC doesn't like this:
InstrProf.h(49) : error C2614: 'llvm::InstrProfRecord' : illegal member initialization: 'Hash' is not a base or member
This reverts r240206.

This consolidates the logic to read instrprof records into the on disk
hash table's lookup trait and makes us copy the counter data instead
of taking references to it as we read. This will simplify further
changes to the format.

Summary: This adds FindGlobalVariableNamed to ExecutionEngine
(plus implementation in MCJIT), which is an analog of
FindFunctionNamed for GlobalVariables.

When a case of INT64_MIN was followed by a case that was greater than
zero, we were overflowing a signed integer here. Since we've sorted
the cases here anyway (and thus currentValue must be greater than
nextValue) it's simple enough to avoid this by using addition rather
than subtraction.

Summary:
Since FunctionMap has llvm::Function pointers as keys, the order in
which the traversal happens can differ from run to run, causing spurious
FileCheck failures. Have CallGraph::print sort the CallGraphNodes by
name before printing them.

If LLVMDebugInfoPDB links against the DIA SDK then the exports file
would contain an INTERFACE_LINK_LIBRARIES property that contained an
absolute path to ``diaguids.lib`` which used a native windows path (interpreted
as escape sequences when LLVMExports.cmake is imported causing
``find_package(LLVM)`` to fail) rather than the correct CMake style path.

This patch changes getRelocationAddend to use ErrorOr and considers it an error
to try to get the addend of a REL section.
If, for example, a x86_64 file has a REL section, that file is corrupted and
we should reject it.
Using ErrorOr is not ideal since we check the section type once per relocation
instead of once per section.
Checking once per section would involve getRelocationAddend just asserting and
callers checking the section before iterating over the relocations.
In any case, this is an improvement and includes a test.

There are 3 types of relocations on MachO
* Scattered
* Section based
* Symbol based
On ELF and COFF relocations are symbol based.
We were in the strange situation that we abstracted over two of them. This makes
section based relocations MachO only.

This commit implements the initial serialization of machine basic blocks in a
machine function. Only the simple, scalar MBB attributes are serialized. The
reference to LLVM IR's basic block is preserved when that basic block has a name.

This patch adds initial support for the -fsanitize=kernel-address flag to Clang.
Right now it's quite restricted: only out-of-line instrumentation is supported, globals are not instrumented, some GCC kasan flags are not supported.
Using this patch I am able to build and boot the KASan tree with LLVMLinux patches from github.com/ramosian-glider/kasan/tree/kasan_llvmlinux.
To disable KASan instrumentation for a certain function attribute((no_sanitize("kernel-address"))) can be used.

What this does is make all symbols that would otherwise start with a .L
(or L on MachO) unnamed.
Some of these symbols still show up in the symbol table, but we can just
make them unnamed.
In order to make sure we produce identical results when going thought assembly,
all .L (not just the compiler produced ones), are now unnamed.
Running llc on llvm-as.opt.bc, the peak memory usage goes from 208.24MB to
205.57MB.

Currently, we canonicalize shuffles that produce a result larger than
their operands with:
shuffle(concat(v1, undef), concat(v2, undef))
->
shuffle(concat(v1, v2), undef)
because we can access quad vectors (see PerformVECTOR_SHUFFLECombine).
This is useful in the general case, but there are special cases where
native shuffles produce larger results: the two-result ops.
We can look through the concat when lowering them:
shuffle(concat(v1, v2), undef)
->
concat(VZIP(v1, v2):0, :1)
This lets us generate the native shuffles instead of scalarizing to
dozens of VMOVs.

The test 'llvm/test/CodeGen/MIR/machine-function.mir' was disabled on
x86 msc18 in r239805 as it failed. My commit r240054 have fixed the

it should pass now.

In a relocation target can take 3 basic forms
* A r_value in scattered relocations.
* A symbol in external relocations.
* A section is non-external relocations.
Have the dump reflect that. With this change we go from
CHECK-NEXT: Extern: 0
CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5)
CHECK-NEXT: Symbol: 0x2
CHECK-NEXT: Scattered: 0
To just
// CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5)
// CHECK-NEXT: Section: __data (2)
Since the relocation is with a section, we print the seciton name and don't
need to say that it is not scattered or external.
Someone motivated can add further special cases for things like
ARM64_RELOC_ADDEND and ARM_RELOC_PAIR.

To same compile time, the analysis to find dense case-clusters in switches is
not done at -O0. However, when the whole switch is dense enough, it is easy to
turn it into a jump table, resulting in much faster code with no extra effort.
