leaq Ltmp1(%rip), %rax
Then continue to codegen the second function where the blocks

this code:
_test_fun: ## @test_fun

Move getJTISymbol from MachineJumpTableInfo to MachineFunction,
...
which is more convenient, and change getPICJumpTableRelocBaseExpr
to take a MachineFunction to match.
Next, move the X86 code that create a PICBase symbol to
X86TargetLowering::getPICBaseSymbol from
X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific
library. This eliminates a 'gross hack', and allows us to
implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
calls it.
This in turn allows us to eliminate the
X86AsmPrinter::printPICJumpTableSetLabel method, which was the
only overload of printPICJumpTableSetLabel.

Rearrange handling of jump tables. Highlights:
...
1. MachineJumpTableInfo is now created lazily for a function the first time
it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the
TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
throughout the compiler that "knows" that jump table entries are always
32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
their kind, instead of at machinefunction creation time.
Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.

For blocks that are not loop headers, just print their loop depth and header BB.

For loop headers, print Inner loop along with the other stuff so it doesn't take

## in Loop: Header=BB1_1 Depth=1
notb %al
testb $1, %al
jne LBB1_8
and:
LBB1_6: ## %while.cond7

## Inside Loop BB1_5 Depth 2
## Inside Loop BB1_1 Depth 1
