As an example of how the custom DiagnosticType can be used to provide
better operand-mismatch diagnostics, add a custom diagnostic for
the imm0_15 operand class used for several system instructions.
Update the tests to expect the improved diagnostic.

"Invalid operand" may be a completely correct diagnostic, but it's often
insufficiently specific to really help identify and fix the problem in
assembly source. Allow a target to specify a more-specific diagnostic kind
for each AsmOperandClass derived definition and use that to provide
more detailed diagnostics when an operant of that class resulted in a
match failure.

include of int_lib.h.

The purpose of this change is to make the C code conform to the pedantic
rules of C99 -- an empty translation unit is not valid. It should have
absolutely no functional impact, and changes nothing about the built
libraries.

The StepOverBreakpoint plan should only explain eStopReasonTrace.  It didn't cause any other exceptional stop reason.

It is both smaller and faster than DenseMap.

Original commit message:
    Allow up to 64 functional units per processor itinerary.

    This patch changes the type used to hold the FU bitset from unsigned to uint64_t.
    This will be needed for some upcoming PowerPC itineraries.

floating around in my client.

EmitZerofill should take a 64-bit size or else it's chopping off large zero-filled global. rdar://11729134

Don't try to print out the live range of a physreg.

DBG_VALUE instructions could be referring to non-existing virtual
registers.

llvm-svn: 159020

There is no need to check for physreg live ranges. They don't exist any
more.

Everyone is using on-demand regunit ranges now.

These functions only operate on virtual registers now, and they all have
live ranges.

Don't depend on LiveIntervals::hasInterval() to determine if a physreg

We don't handle exceptions yet, so we treat them as sinks. ExprEngine
hardcodes messages that are known to raise Objective-C exceptions like -raise,
but it was only checking for +raise:format: and +raise:format:arguments: on
NSException itself, not subclasses.
