Justin Bogner 3135ba9b38 AsmPrinter: Use emitGlobalConstantFP to emit elements of constant data
It's strange to duplicate the logic for emitting FP values into
emitGlobalConstantDataSequential, and it's even stranger that we end
up printing the verbose assembly comments differently between the two
paths. Just call into emitGlobalConstantFP rather than crudely
duplicating its logic.

Kristof Beyls e6b876f4e5 Fix constant folding through bitcasts by no longer relying on undefined behaviour (converting NaN values between float and double).
SelectionDAG::getConstantFP(double Val, EVT VT, bool isTarget);
should not be used when Val is not a simple constant (as the comment in
SelectionDAG.h indicates). This patch avoids using this function
when folding an unknown constant through a bitcast, where it cannot be
guaranteed that Val will be a simple constant.

Jakob Stoklund Olesen 7d33c5739f Don't add CFG edges for redundant conditional branches.
IR that hasn't been through SimplifyCFG can look like this:

  br i1 %b, label %r, label %r

Make sure we don't create duplicate Machine CFG edges in this case.

Fix the machine code verifier to accept conditional branches with a
single CFG edge.

Jim Grosbach 581da64241 Simplify printing of ARM shifted immediates.
Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
 displayed.

Nick Lewycky 6208a2fd66 Emit trailing padding on constant vectors when TargetData says that the vector
is larger than the sum of the elements (including per-element padding).

Cameron Zwarich 338d362200 Roll r127459 back in:
Optimize trivial branches in CodeGenPrepare, which often get created from the
lowering of objectsize intrinsics. Unfortunately, a number of tests were relying
on llc not optimizing trivial branches, so I had to add an option to allow them
to continue to test what they originally tested.

This fixes <rdar://problem/8785296> and <rdar://problem/9112893>.

Reid Spencer 6e87ec4351 For PR1319:
Remove && from the end of the lines to prevent tests from throwing run
lines into the background. Also, clean up places where the same command
is run multiple times by using a temporary file.
