For x86, canonicalize max
...
(x > y) ? x : y
=>
(x >= y) ? x : y
So for something like
(x - y) > 0 : (x - y) ? 0
It will be
(x - y) >= 0 : (x - y) ? 0
This makes is possible to test sign-bit and eliminate a comparison against
zero. e.g.
subl %esi, %edi
testl %edi, %edi
movl $0, %eax
cmovgl %edi, %eax
=>
xorl %eax, %eax
subl %esi, $edi
cmovsl %eax, %edi

Turn a few more inline asm errors into "emitErrors" instead of fatal errors.

Before we'd get:
$ clang t.c
fatal error: error in backend: Invalid operand for inline asm constraint 'i'!
Now we get:
$ clang t.c
t.c:16:5: error: invalid operand for inline asm constraint 'i'!
"movq (%4), %%mm0\n"

Which at least gets us the inline asm that is the problem.

Test "merging" of typedef types across distinct modules. At present,
...
the AST reader doesn't actually perform a merge, because name lookup
knows how to merge identical typedefs together.
As part of this, teach C/Objective-C name lookup to return multiple
results in all cases, rather than first digging through the attributes
to see if the value is overloadable. This way, we'll catch ambiguous
lookups in C/Objective-C.

Remove the restriction that target intrinsics can only involve legal types. Targets can perfects well support intrinsics on illegal types, as long as they are prepared to perform custom expansion during type legalization. For example, a target where i64 is illegal might still support the i64 intrinsic operation using pairs of i32's. ARM already does some expansions like this for non-intrinsic operations.

Eliminate the uglified keyword __import_module__ for importing
...
modules. This leaves us without an explicit syntax for importing
modules in C/C++, because such a syntax needs to be discussed
first. In Objective-C/Objective-C++, the @import syntax is used to
import modules.
Note that, under -fmodules, C/C++ programs can import modules via the
#include mechanism when a module map is in place for that header. This
allows us to work with modules in C/C++ without committing to a syntax.
