Uhrain! Fixes PR10318.

Combine redundant base classes and such. No indended functional change.

llvm-svn: 135085

Make sure we don't combine a large displacement and a frame index in the same addressing mode on x86-64.  It can overflow, leading to a crash/miscompile.

They're all Thumb2 only, not just some of them. More refactoring cleanup
coming.

llvm-svn: 135081

Some pysical registers create split solutions that would spill anywhere.
They should not even be considered in future multi-way global splits.

This does not affect code generation (yet).

llvm-svn: 135080

Refactor out checking for displacements on x86-64 addressing modes.  No functionality change.  Refactoring in preparation for an additional safety check in FoldOffsetIntoAddress.

format string checking: long and int have the same widths on 32-bit, so we shouldn't warn about using
an "int" format specifier with a "long" type in 32-bit.

This is in preparation of supporting multiple global split candidates in
a single live range split operation.

it as used.  Otherwise, we can fail to instantiate or validate the destructor,
which can lead to crashes in IR gen like PR10351.

The immediate is of limited range and the operand type should reflect that.

[arcmt] For properties rewrite 'assign' -> 'weak or unsafe_unretained', 'retain' -> 'strong', and add
'weak or unsafe_unretained' when 'assign' is missing. rdar://9496219&9602589.

It's not safe to fold (fptrunc (sqrt (fpext x))) to (sqrtf x) if there is another use of sqrt. rdar://9763193

Catch potential cascading errors on a malformed so_reg operand and bail after
the first error.

Add some tests for the diagnostics we do want.

__unknown_anytype, and rewrite such message sends correctly.

I had to bite the bullet and actually add a debugger support mode for this
one, which is a bit unfortunate, but there really isn't anything else
I could imagine doing;  this is clearly just debugger-specific behavior.

Make it also available in ObjC++ propeties. Use common code for
objc and objc++ so they don't diverge. // rdar://9740328

Now works for parsing register shifted register and register shifted
immediate arithmetic instructions, including the 'rrx' rotate with extend.

Re-relax conversion specifier checking for printf format strings and conversion specifiers.  My recent change was a mistake.
