Fix PR4533, which is about buggy codegen in x86-64 -static mode.
...
Basically, using:
lea symbol(%rip), %rax
is not valid in -static mode, because the current RIP may not be
within 32-bits of "symbol" when an app is built partially pic and
partially static. The fix for this is to compile it to:
lea symbol, %rax
It would be better to codegen this as:
movq $symbol, %rax
but that will come next.
The hard part of fixing this bug was fixing abi-isel, which was actively
testing for the wrong behavior. Also, the RUN lines are completely impossible
to understand what they are testing. To help with this, convert the -static
x86-64 codegen tests to use filecheck. This is much more stable and makes it
more clear what the codegen is expected to be.

If -fomit-frame-pointer is used, we still need to record when the %esp register
...
is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.
On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!
This is a Good Thing(tm)!!!

Targets sometimes assign fixed stack object to spill certain callee-saved

registers based on dynamic conditions. For example, X86 EBP/RBP, when used as
frame register has to be spilled in the first fixed object. It should inform
PEI this so it doesn't get allocated another stack object. Also, it should not
be spilled as other callee-saved registers but rather its spilling and restoring
are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice.

Recommit r74952 with a bug fix:
...
DWARF requires frame moves be specified at specific times. If you have a
prologue like this:
__Z3fooi:
Leh_func_begin1:
LBB1_0: ## entry
pushl %ebp
Llabel1:
movl %esp, %ebp
Llabel2:
pushl %esi
Llabel3:
subl $20, %esp
call "L1$pb"
"L1$pb":
popl %esi
The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp,
%ebp" makes %ebp the new stack frame register, so that needs to be specified in
DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs
to be specified in DWARF.
Before, all of this logic was in one method. This didn't work too well, because
as you can see there are multiple FDE line entries that need to be created.
This fix creates the "MachineMove" objects directly when they're needed; instead
of waiting until the end, and losing information.
There is some ugliness where we generate code like this:
LBB22_0: ## entry
pushl %ebp
Llabel280:
movl %esp, %ebp
Llabel281:
Llabel284:
pushl %ebp <----------
pushl %ebx
pushl %edi
pushl %esi
Llabel282:
subl $328, %esp
Notice the extra "pushl %ebp". If we generate a "machine move" instruction in
the FDE for that pushl, the linker may get very confused about what value %ebp
should have when exitting the function. I.e., it'll give it the value %esp
instead of the %ebp value from the first "pushl". Not to mention that, in this
case, %ebp isn't modified in the function (that's a separate bug). I put a small
hack in to get it to work. It might be the only solution, but should be
revisited once the above case is fixed.

Make the code that updates ScalarEvolution's internal state in response

to a loop deletion more thorough. Don't prune the def-use tree search at
instructions that don't have SCEVs computed, because an instruction with
a user that has a computed SCEV may itself lack a computed SCEV. Also,
remove loop-related values from the ValuesAtScopes and
ConstantEvolutionLoopExitValues maps as well.
