chunked schedule set via OMP_SCHEDULE. The bug was that chunk=1

This commit adds new classes CompatRule and MergeRule to Attributes.td,
which are used to generate code to check attribute compatibility and
merge attributes of the caller and callee.

r243347 was intended to support a change to LSR (r243348). That change
to LSR has since had to be reverted (r243939) because it was buggy, and
now the code added in r243347 is untested and unexercised. Given that,
I think it is appropriate to revert r243347 for now, with the intent of
adding it back in later if I get around to checking in a fixed version
of r243348.

Only when we check for wrapping we want to use the store size, for all
other cases we use the alloc size now.

This finishes the effort to port python-wrapper.swig code over to
using PythonDataObjects.
Also included in this patch is the removal of `PyCallable` from
`python-wrapper.swig`, as it is no longer used after having been
replaced by `PythonCallable` everywhere.
There might be additional cleanup as followup patches, but it should
be all fairly simple and minor.

Update the ThinLTO function importing test to use DAG forms of checks so
that it is more tolerant of changes to relative ordering between
imported decls/defs. This reduces the number of changes required by the
comdat importing patch I am sending for review shortly.

In r244063, I had caused these builtins to call the same-named library
functions, __atomic_*_fetch_SIZE. However, this was incorrect: while
those functions are in fact supported by GCC's libatomic, they're not
documented by the spec (and gcc doesn't ever call them).
Instead, you're /supposed/ to call the __atomic_fetch_* builtins and
then redo the operation inline to return the final value.

ShrinkWrapping does not understand exception handling constraints for now, so
make sure we do not mess with them by aborting on functions that use EH
funclets.

Summary:
This change addresses two possible instances of user error / confusion when
merging sampled profile data.
Previously any input that didn't match the raw or processed instrumented format
would automatically be interpreted as instrumented profile text format data.
No error would be reported during the merge.
Example:
If foo-sampled.profdata and bar-sampled.profdata are binary sampled profiles:
Old behavior:
$ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -output foobar-sampled.profdata
$ llvm-profdata show -sample foobar-sampled.profdata
error: foobar-sampled.profdata:1: Expected 'mangled_name:NUM:NUM', found lprofi
This change adds basic checks for valid input data when assuming text input.
It also makes error messages related to file format validity more specific about
the assumbed profile data type.
New behavior:
$ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -o foobar-sampled.profdata
error: foo.profdata: Unrecognized instrumentation profile encoding format
Perhaps you forgot to use the -sample option?

Switch to MC for instruction printing.
This encompasses several changes which are all interconnected:
- Use the MC framework for printing almost all instructions.
- AsmStrings are now live.
- This introduces an indirection between LLVM vregs and WebAssembly registers,
and a new pass, WebAssemblyRegNumbering, for computing a basic the mapping.
This addresses some basic issues with argument registers and unused registers.
- The way ARGUMENT instructions are handled no longer generates redundant
get_local+set_local for every argument.
This also changes the assembly syntax somewhat; most notably, MC's printing
does not use sigils on label names, so those are no longer present, and
push/pop now have a sigil to keep them unambiguous.
The usage of set_local/get_local/$push/$pop will continue to evolve
significantly. This patch is just one step of a larger change.

LLVM Missing the following instructions: fadd\fdiv\fmul\fsub\fsubr\fdivr.

PyCallable is a class that exists solely within the swig wrapper
code. PythonCallable is a more generic implementation of the same
idea that can be used by any Python-related interop code, and lives
in PythonDataObjects.h
The CL is mostly mechanical, and it doesn't cover every possible
user of PyCallable, because I want to minimize the impact of this
change (as well as making it easier to figure out what went wrong
in case this causes a failure). I plan to finish up the rest of
the changes in a subsequent patch, culminating in the removal of
PyCallable entirely.

Summary:
This patch changes ARMV5, ARMV5E, ARMV6SM, ARMV6HL, ARMV7, ARMV7L,
ARMV7HL, ARMV7EM to be treated as aliases for the corresponding
standard architectures, instead of as actual architectures.

The C++ spec (3.6.1.3) says "The function `main` shall not be used within a program". This implies that it cannot recurse, so add the norecurse attribute to help the midend out a bit.
