3baf4622e9 Change the default attributes for llvm.prefetch to inaccessiblemem_or_argmemonly 
so that we can perform some optimizations across it.

Fixes PR32365

8c1de765fa [Bitcode] Fix accidental syntax errors in compatibility tests 
We used automated tools to update our IR to its current syntax in commit
21f77df7(r247378). While it correctly updated the CHECK lines in our
compatibility tests, the IR should have remained untouched.  This commit
fixes the syntax errors.

6823d9fe99 [IR] Limit bits used for CallingConv::ID, update tests 
Use 10 bits to represent calling convention ID's instead of 13, and
update the bitcode compatibility tests accordingly. We now error-out in
the bitcode reader when we see bad calling conv ID's.

Thanks to rnk and dexonsmith for feedback!

65b92c4f37 [opaque pointer type] Add textual IR support for explicit type parameter for global aliases

plain = re.compile(alias_match_prefix + r" (.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|addrspacecast|\[\[[a-zA-Z]|\{\{).*$)")
cast  = re.compile(alias_match_prefix + r") ((?:bitcast|inttoptr|addrspacecast)\s*\(.* to (.*?)(| addrspace\(\d+\) *)\*\)\s*(?:;.*)?$)")
gep   = re.compile(alias_match_prefix + r") ((?:getelementptr)\s*(?:inbounds)?\s*\((?P<type>.*), (?P=type)(?:\s*addrspace\(\d+\)\s*)?\* .*\)\s*(?:;.*)?$)")

def conv(line):
  m = re.match(cast, line)

    return m.group(1) + " " + m.group(3) + ", " + m.group(2)

for line in sys.stdin:

apply.sh:
for name in "$@"
do
  python3 `dirname "$0"`/update.py < "$name" > "$name.tmp" && mv "$name.tmp" "$name"
  rm -f "$name.tmp"
done

The actual commands:
From llvm/src:
find test/ -name *.ll | xargs ./apply.sh
From llvm/src/tools/clang:
find test/ -name *.mm -o -name *.m -o -name *.cpp -o -name *.c | xargs -I '{}' ../../apply.sh "{}"
From llvm/src/tools/polly:
find test/ -name *.ll | xargs ./apply.sh

b87fbd089e IR: Add a broad bitcode compatibility test 
Successive versions of LLVM should retain the ability to parse bitcode
generated by old releases of the compiler.  This adds a bitcode format
compatibility test, which is intended to provide good (albeit not
entirely exhaustive) coverage of the current LangRef.

This also includes compatibility tests for LLVM 3.6.  After every 3.X.0
release, the compatibility.ll file from the 3.X branch should be copied
to compatibility-3.X.ll on trunk, and the 3.X.0 release used to generate
a corresponding bitcode file.
