8be6039072 Revert r238305: [PM] Use a simpler technique to drop optional analysis
manager arguments...

I have no idea why, but compilers seem to hate this and its late, so I'm
not going to debug it. :: sigh :: This is why we can't have nice things.

910146c989 [PM] Use a simpler technique to drop optional analysis manager arguments
when invoking run methods.

This technique was suggested by Dinesh Dwivedi who also wrote the
original patch. During the code review, they explained to me that this
isn't a fully general technique as we need to know the signatures of the
method candidates. Since this is really a narrower utility, I switched
the names and structure to be more clearly a specialized run method
invoke helper and commented it accordingly. I still think this is
a pretty big win.

Very sorry to Dinesh for the extreme delay in landing this patch. I've
been far to busy poking at other things.

60c91c28e4 [X86] Implement the support for shrink-wrapping.
With this patch the x86 backend is now shrink-wrapping capable
and this functionality can be tested by using the
-enable-shrink-wrap switch.

The next step is to make more test and enable shrink-wrapping by
default for x86.

34afa06cf2 [inliner] Fix the early-exit of the inline cost analysis to correctly
model the dense vector instruction bonuses.

Previously, this code really didn't effectively compute the density of
inlined vector instructions and apply the intended inliner bonus. It
would try to compute it repeatedly while analyzing the function and
didn't handle the case where future vector instructions would tip the
scales back towards the bonus.

Instead, speculatively apply all possible bonuses to the threshold
initially. Once we *know* that a certain bonus can not be applied,
subtract it. This should delay early bailout enough to get much more
consistent results without actually causing us to analyze huge swaths of
code. I expect some (hopefully mild) compile time hit here, and some
swings in performance, but this was definitely the intended behavior of
these bonuses.

This also dramatically simplifies the computation of the bonuses to not
interact with each other in confusing ways. The previous code didn't do
a good job of this and the values for bonuses may be surprising but are
at least now clearly written in the code.

Finally, fix code to be in line with comments and use zero as the
bailout condition.

Patch by Easwaran Raman, with some comment tweaks by me to try and
further clarify what is going on with this code.

90b5eb2319 [PlaceSafepoints] Entry safepoint location doesn't need to be a terminator
Long ago, the poll insertion code assumed that the insertion site was a terminator.  As a result, the entry selection code would split a basic block to ensure it could pass a terminator.  The insertion code was updated quite a while ago - possibly before it ever landed upstream - but the now redundant work was never removed.  

While I'm at it, remove a comment which doesn't apply to the upstreamed code.  

NFC intended.

890a876e0e Print "lock \t foo" instead of "lock \n foo".

on which line the "lock" is in.

75775939fa AsmMatcherEmitter: Add an option to override custom converters for InstAlias
If there is an InstAlias defined for an instruction that had a custom
converter (AsmMatchConverter), then when the alias is matched,
the custom converter will be used rather than the converter generated
by the InstAlias.

This patch adds the UseInstAsmMatchConverter field to the InstAlias
class, which allows you to override this behavior and force the
converter generated by the InstAlias to be used.

This is required for some future improvemnts to the R600 assembler.
