This adds an instcombine matcher for code that attempts to perform signed
saturating arithmetic by casting to a higher type. Unsigned cases are already
matched, this adds extra matches for the more complex signed cases, which
involves matching the min(max(add a b)) nodes with proper extends to ensure
legality.

    Summary: This patch removes `shared_ptr::make_shared` as it is not part of the standard. This patch also adds __create_with_cntrl_block, which is a help function that can be used in std::allocate_shared and std::make_shared. This is the third patch (out of 4) from D66178.

MachineRegisterInfo::createGenericVirtualRegister sets
RegClassOrRegBank to static_cast<RegisterBank *>(nullptr).
MIParser on the other hand doesn't. When we attempt to constrain
Register Class on such VReg, additional COPY is generated.
This way we avoid COPY instructions showing in test that have MIR
input while they are not present with llvm-ir input that was used
to create given MIR for a -run-pass test.

Select vector G_ADD for MIPS32 with MSA. We have to set bank
for vector operands to fprb and selectImpl will do the rest.
__builtin_msa_addv_<format> will be transformed into G_ADD
in legalizeIntrinsic and selected in the same way.
__builtin_msa_addvi_<format> will be directly selected into
ADDVI_<format> in legalizeIntrinsic. MIR tests for it have
unnecessary additional copies. Capture current state of tests
with run-pass=legalizer with a test in test/CodeGen/MIR/Mips.

This re-commits r375152 which was pulled in r375233 because it broke
the EXPENSIVE_CHECKS bot on Windows.

The reason for the failure was a bug in the pass that the commit turned
on by default. This patch fixes that bug and turns the pass back on.
This patch has been verified on the buildbot that originally failed
thanks to Simon Pilgrim.

Currently injected-sources-native.test fails with "Expected<T>
value was in success state.
(Note: Expected<T> values in success mode must still be checked
prior to being destroyed)"
when llvm is compiled with LLVM_ENABLE_ABI_BREAKING_CHECKS in Release.

The problem is that getStringForID returns Expected<StringRef>
and Expected value must always be checked, even if it is in success state.
Checking with assert only helps in Debug and is wrong.

Within the last two weeks, the Builtins-*-sunos :: clear_cache_test.c started to FAIL
on Solaris.  Running it under truss shows

  mmap(0x00000000, 128, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANON, 0, 0) Err#22 EINVAL
  _exit(1)

While there are several possible reasons mmap can return EINVAL on Solaris, it turns
out it's this one (from mmap(2)):

  MAP_ANON  was  specified,  but the file descriptor was not
   -1.

And indeed even the Linux mmap(2) documents this as unportable:

  MAP_ANONYMOUS
          The mapping is not backed by any file; its contents are initial‐
          ized to zero.  The fd argument is ignored; however, some  imple‐
          mentations require fd to be -1 if MAP_ANONYMOUS (or MAP_ANON) is
          specified, and portable applications should  ensure  this.   The

This patch follows this advise.  Tested on x86_64-pc-linux-gnu, amd64-pc-solaris2.11
and sparcv9-sun-solaris2.11.

Summary:
With this patch, only the no-argument form of `Reset()` remains in
PythonDataObjects.   It also deletes PythonExceptionState in favor of
PythonException, because the only call-site of PythonExceptionState was
also using Reset, so I cleaned up both while I was there.
