[AArch64]Fix the pattern match failure for v1i8/v1i16/v1i32 types.
Currently we have such types as legal vector types. The DAG combiner may generate some DAG nodes having such types but we don't have patterns to match them.
E.g. a load i32 and a bitcast i32 to v1i32 will be combined into a load v1i32:
bitcast (load i32) to v1i32 -> load v1i32.
So this patch fixes such problems for load/dup instructions.
If v1i8/v1i16/v1i32 are not legal any more, the code in this patch can be deleted. So I also add some FIXME.

[Stackmap] Liveness Analysis Pass
This optional register liveness analysis pass can be enabled with either
-enable-stackmap-liveness, -enable-patchpoint-liveness, or both. The pass
traverses each basic block in a machine function. For each basic block the
instructions are processed in reversed order and if a patchpoint or stackmap
instruction is encountered the current live-out register set is encoded as a
register mask and attached to the instruction.
Later on during stackmap generation the live-out register mask is processed and
also emitted as part of the stackmap.
This information is optional and intended for optimization purposes only. This
will enable a client of the stackmap to reason about the registers it can use
and which registers need to be preserved.

[block-freq] Refactor LiveInterals::getSpillWeight to use the new MachineBlockFrequencyInfo methods.
This is slightly more interesting than the previous batch of changes.
Specifically:
1. We refactor getSpillWeight to take a MachineBlockFrequencyInfo (MBFI)
object. This enables us to completely encapsulate the actual manner we
use the MachineBlockFrequencyInfo to get our spill weights. This yields
cleaner code since one does not need to fetch the actual block frequency
before getting the spill weight if all one wants it the spill weight. It
also gives us access to entry frequency which we need for our
computation.
2. Instead of having getSpillWeight take a MachineBasicBlock (as one
might think) to look up the block frequency via the MBFI object, we
instead take in a MachineInstr object. The reason for this is that the
method is supposed to return the spill weight for an instruction
according to the comments around the function.

[inliner] Completely change (and fix) how the inline cost analysis
handles terminator instructions.
The inline cost analysis inheritted some pretty rough handling of
terminator insts from the original cost analysis, and then made it much,
much worse by factoring all of the important analyses into a separate
instruction visitor. That instruction visitor never visited the
terminator.
This works fine for things like conditional branches, but for many other
things we simply computed The Wrong Value. First example are
unconditional branches, which should be free but were counted as full
cost. This is most significant for conditional branches where the
condition simplifies and folds during inlining. We paid a 1 instruction
tax on every branch in a straight line specialized path. =[
Oh, we also claimed that the unreachable instruction had cost.
But it gets worse. Let's consider invoke. We never applied the call
penalty. We never accounted for the cost of the arguments. Nope. Worse
still, we didn't handle the *correctness* constraints of not inlining
recursive invokes, or exception throwing returns_twice functions. Oops.
See PR18206. Sadly, PR18206 requires yet another fix, but this
refactoring is at least a huge step in that direction.

Swap around EXPECT_EQ() arguments orders for more natural gtest Failure messages
Somewhat counterintuitively the first arg in gtest is treated as the
expectation.
No change to the tests themselves.

Add missing escape characters to the new Regex::escape() function
The old AddFixedStringToRegEx() it was based on got away with this for the
longest time, but the problem became easy to spot after the cleanup in r197096.
Also add a quick unit test to cover regex escaping.

Check for null pointer before dereferencing. A careless typo on my part.
I don't know why this did not show up earlier. This code has been
around for ages.

Fix Incorrect CHECK message [0-31]+ in test case.
In regular expression, [0-31]+ equals to [0-3]+, not the number from
0 to 31. So change it to [0-9]+.
