CL 2.0 introduced atomics and generic address space so there were
only one set of APIs for doing atomics, however since CL 3.0
makes generic address space optional, there has to be new sets
of atomic interfaces to handle that cases.

This patch adds `#pragma clang deprecated` to enable deprecation of
preprocessor macros.
The macro must be defined before `#pragma clang deprecated`. When
deprecating a macro a custom message may be optionally provided.
Warnings are emitted at the use site of a deprecated macro, and can be
controlled via the `-Wdeprecated` warning group.
This patch takes some rough inspiration and a few lines of code from
https://reviews.llvm.org/D67935.

@kpn pointed out that the global variable initialization functions didn't
have the "strictfp" metadata set correctly, and @rjmccall said that there
was buggy code in SetFPModel and StartFunction, this patch is to solve
those problems. When Sema creates a FunctionDecl, it sets the
FunctionDeclBits.UsesFPIntrin to "true" if the lexical FP settings
(i.e. a combination of command line options and #pragma float_control
settings) correspond to ConstrainedFP mode. That bit is used when CodeGen
starts codegen for a llvm function, and it translates into the
"strictfp" function attribute. See bugs.llvm.org/show_bug.cgi?id=44571

Summary:
Set the TargetCPUName for AIX to default to pwr7, removing the setting
of it based on the major/minor of the OS version, which previously
set it to pwr4 for AIX 7.1 and earlier. The old code would also set it to
pwr4 when the OS version was not specified and with the change, it will
default it to pwr7 in all cases.

The implementation of -fminimize-whitespace (D104601) revised the logic
when to emit newlines. There was no case to handle when more than
8 lines were skippped in -P (DisableLineMarkers) mode and instead fell
through the case intended for -fminimize-whitespace, i.e. emit nothing.
This patch will emit one newline in this case.
The newline logic is slightly reorganized. The `-P -fminimize-whitespace`
case is handled explicitly and emitting at least one newline is the new
fallback case. The choice between emitting a line marker or up to
7 empty lines is now a choice only with enabled line markers. The up to
8 newlines likely are fewer characters than a line directive, but
in -P mode this had the paradoxic effect that it would print up to
7 empty lines, but none at all if more than 8 lines had to be skipped.
Now with DisableLineMarkers, we don't consider printing empty lines
(just start a new line) which matches gcc's behavior.
The line-directive-output-mincol.c test is replaced with a more
comprehensive test skip-empty-lines.c also testing the more than
8 skipped lines behaviour with all flag combinations.

When substitution failed on the first constrained template argument (but
only the first), we would assert / crash. Checking for failure was only
being performed from the second constraint on.
This changes it so the checking is performed in that case,
and the code is also now simplified a little bit to hopefully
avoid this confusion.

The Clang interpreter's bytecode uses a packed stream of bytes
representation, but also wants to have some opcodes take pointers as
arguments, which are currently embedded in the bytecode directly.
However, CHERI, and thus Arm's upcoming experimental Morello prototype,
provide spatial memory safety for C/C++ by implementing language-level
(and sub-language-level) pointers as capabilities, which track bounds,
permissions and validity in hardware. This uses tagged memory with a
single tag bit at every capability-aligned address, and so storing
pointers to unaligned addresses results in the tag being stripped,
leading to a tag fault when the pointer is ultimately dereferenced at a
later point.
In order to support a stricter C/C++ implementation like CHERI, we no
longer store pointers directly in the bytecode, instead storing them in
a table and embedding the index in the bytecode.

ClassTemplateSpecializationDecl not within a ClassTemplateDecl
represents an explicit instatiation of a template and so should be
handled as if it were a normal CXXRecordDecl. Unfortunately, having an
equivalent for FunctionTemplateDecl remains a TODO in ASTDumper's
VisitFunctionTemplateDecl, with all the explicit instantiations just
being emitted inside the FunctionTemplateDecl along with all the other
specializations, meaning we can't easily support explicit function
instantiations in update_cc_test_checks.

This patch extends pragma float_control syntax, and also adds support

Currently, we prohibit this pragma from appearing within a language
linkage specification, but this is useful functionality that is
supported by MSVC (which is where we inherited this feature from).
This patch allows you to use the pragma within an extern "C" {} (etc)
block.
Previously, with AllowShortEnumsOnASingleLine disabled, enums that would have otherwise fit on a single line would always put the opening brace on its own line.
This patch ensures that these enums will only put the brace on its own line if the existing attachment rules indicate that it should.

The device runtime contains several calls to __kmpc_get_hardware_num_threads_in_block
and __kmpc_get_hardware_num_blocks. If the thread_limit and the num_teams are constant,
these calls can be folded to the constant value.
In commit D106033 we have the optimization phase. This commit adds the attributes to
the outlined function for the grid size. the two attributes are `omp_target_num_teams` and
`omp_target_thread_limit`. These values are added as long as they are constant.
Two functions are created `getNumThreadsExprForTargetDirective` and
`getNumTeamsExprForTargetDirective`. The original functions `emitNumTeamsForTargetDirective`
and `emitNumThreadsForTargetDirective` identify the expresion and emit the code.
However, for the Device version of the outlined function, we cannot emit anything.
Therefore, this is a first attempt to separate emision of code from deduction of the
values.

This reverts commit e8a64e5491.
We have the basic infrastructure in place. We can recover from simple errors
(recovering from errors in template instantiations is not yet supported). It
