There was missing nullptr check before a call to getSection() in
recordRelocation. This would result in a segfault in code like the attached
test.
This adds the missing check and a test which makes sure we get the expected
error output.

Summary:
We would like the UMR debugging tool[0] to be able to provide
disassembly for currently live waves based on plain memory
dumps, and we want to leverage the LLVM disassembler for this.
This mostly works, except that UMR clearly can't provide real
symbol info, so it wants to set DisInfo == nullptr.

This patch moves the logic that collects and analyzes dispatch events to the
DispatchStatistics view.
Added flag -dispatch-stats to print statistics related to the dispatch logic.

This is a redo of D45296.
It looks like the random stack-protector issues I was getting were coming from
my Android emulator, and updating everything all around and relaunching stuff
ended up making it go away.
I guess I'll have to see how it behaves on the bots.
Only additional change from the previous CL is some `const` were appropriate.

Summary:
This type is created on-demand and used as the base type for array
ranges. Since it is "special", its construction did not go through the
createTypeDIE function and so it was never inserted into the accelerator
table, although it clearly belongs there.
I add an explicit addAccelType call to insert it into the table.
During review, we also decided to rename the type to something more
unique to avoid confusion in case the user has own "sizetype" type. The
new name for the type size __ARRAY_SIZE_TYPE__.

Failed<ErrorInfoBase>() did not compile, because it was attempting to
create a copy of the Error object when passing it to the nested matcher,
which was not possible because ErrorInfoBase is abstract.
This commit fixes the problem by making sure we pass the ErrorInfo
object by reference, which also improves the handling of non-abstract
objects, as we avoid potentially slicing an object during the copy.

HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the

Improve the alias analysis to account for cases where we
know that src/dst pairs cannot alias due to things like
TBAA. As we know they are noalias, we know no dependency
can occur. Also fixes issues around the size parameter
to AA being incorrect.

In the presence of variable-sized stack objects, we always picked the
base pointer when resolving frame indices if it was available.
This makes us hit an assert where we can't reach the emergency spill
slot if it's too far away from the base pointer. Since on AArch64 we
decide to place the emergency spill slot at the top of the frame, it
makes more sense to use FP to access it.
The changes here don't affect only emergency spill slots but all the
frame indices. The goal here is to try to choose between FP, BP and SP
so that we minimize the offset and avoid scavenging, or worse, asserting
when trying to access a slot allocated by the scavenger.
Previously discussed here: https://reviews.llvm.org/D40876.

Summary:
For OS type AMDPAL, the scratch descriptor is loaded from offset 0 of
the GIT, whose 32 bit pointer is in s0 (s8 for gfx9 merged shaders).
This commit fixes that to use offset 0x10 instead of offset 0 for a
compute shader, per the PAL ABI spec.
V2: Ensure s0 (s8 for gfx9 merged shader) is marked live-in when loading
scratch descriptor from GIT.

The BroadwellModelProcResources had an entry for HWPort5, which is a Haswell
resource, and not a Broadwell processor resource. That entry was added to the
Broadwell model because variable blends were consuming it.
This was clearly a typo (the resource name should have been BWPort5), which
unfortunately was never caught before. It was not reported as an error because
HWPort5 is a resource defined by the Haswell model. It has been found when
testing some code with llvm-mca: the list of resources in the resource pressure
view was odd.
This patch fixes the issue; now variable blend instructions consume 2 cycles on
BWPort5 instead of HWPort5. This is enough to get rid of the extra (spurious)
entry in the BroadWellModelProcResources table.

It looks like we introduced isprint8 way back in r169417 to be used on
getopt's short_options, which we sometimes set to values which are out
of range for normal chars to indicate options with no short form.
However, this is not how the function is used in the Args class, where
we explicitly process a string character by character.
This removes the last external dependency from the Args class.

These are not used anywhere in the Args class. They should have been
moved as a part of r327110 (Moving Option parsing from Args to Options),
but I did not notice them then.
This does not affect the layering in any way, but in makes sense for the
structs to be defined in the near the code that uses them.
llvm-svn: 329679
Summary:
The idea behind this is to move the functionality which depend on other lldb
classes into a separate class. This way, the Args class can be turned
into a lightweight arc+argv wrapper and moved into the lower lldb
layers.

This cleans up a number of operations that only claimed te use EFLAGS
due to using DF. But no instructions which we think of us setting EFLAGS
actually modify DF (other than things like popf) and so this needlessly
creates uses of EFLAGS that aren't really there.
In fact, DF is so restrictive it is pretty easy to model. Only STD, CLD,
and the whole-flags writes (WRFLAGS and POPF) need to model this.
I've also somewhat cleaned up some of the flag management instruction
definitions to be in the correct .td file.
Adding this extra register also uncovered a failure to use the correct
datatype to hold X86 registers, and I've corrected that as necessary
here.
