Revert the load slicing done in r190870.

To avoid regressions with bitfield optimizations, this slicing should take place
later, like ISel time.

FileCheck refactor: use enum instead of bunch of bools

Use function's argument instead of the global flag.

For now it happens the argument is always the same.

COFF: Ensure that objects produced by LLVM link with /safeseh

Summary:
We indicate that the object files are safe by emitting a @feat.00
absolute address symbol.  The address is presumably interpreted as a
bitfield of features that the compiler would like to enable.  Bit 0 is
documented in the PE COFF spec to opt in to "registered SEH", which is
what /safeseh enables.

LLVM's object files are safe by default because LLVM doesn't know how to
produce SEH handlers.

Fix a constant folding address space place I missed.

If address space 0 was smaller than the address space
in a constant inttoptr/ptrtoint pair, the wrong mask size
would be used.

Fix X86 subtarget to not overwrite the autodetected features by calling InitMCProcessorInfo right after detecting them. Instead add a new function that only updates the scheduling model and call that.

Prevent extra calls to ToggleFeature for Feature64Bit and FeatureCMOV if they've already been enabled. The extra call ends up clearing the bit in FeatureBits since its a 'toggle'. Can't prove that anything was broken because of this since I don't think the FeatureBits for these are used.

Make DynamicLibrary use ManagedStatic. This is pretty simple and should just work as 
advertised - but it does have the caveat that calls to DynamicLibrary::AddSymbol will 
"reset" if you shutdown llvm and try to come back for seconds.  This is a subtle 
behavior change, but I'm assuming that nobody is affected by it.

[SystemZ] Add unsigned compare-and-branch instructions

For some reason I never got around to adding these at the same time as
the signed versions.  No idea why.

I'm not sure whether this SystemZII::BranchC* stuff is useful, or whether
it should just be replaced with an "is normal" flag.  I'll leave that
for later though.

There are some boundary conditions that can be tweaked, such as preferring
unsigned comparisons for equality with [128, 256), and "<= 255" over "< 256",
but again I'll leave those for a separate patch.
