Include inlined functions when figuring out a contiguous address range
Checking this in for Antonio Afonso:
This diff changes the function LineEntry::GetSameLineContiguousAddressRange so that it also includes function calls that were inlined at the same line of code.
My motivation is to decrease the step over time of lines that heavly rely on inlined functions. I have multiple examples in the code base I work that makes a step over stop 20 or mote times internally. This can easly had up to step overs that take >500ms which I was able to lower to 25ms with this new strategy.
The reason the current code is not extending the address range beyond an inlined function is because when we resolve the symbol at the next address of the line entry we will get the entry line corresponding to where the original code for the inline function lives, making us barely extend the range. This then will end up on a step over having to stop multiple times everytime there's an inlined function.
To check if the range is an inlined function at that line I also get the block associated with the next address and check if there is a parent block with a call site at the line we're trying to extend.
To check this I created a new function in Block called GetContainingInlinedBlockWithCallSite that does exactly that. I also added a new function to Declaration for convinence of checking file/line named CompareFileAndLine.
To avoid potential issues when extending an address range I added an Extend function that extends the range by the AddressRange given as an argument. This function returns true to indicate sucess when the rage was agumented, false otherwise (e.g.: the ranges are not connected). The reason I do is to make sure that we're not just blindly extending complete_line_range by whatever GetByteSize() we got. If for some reason the ranges are not connected or overlap, or even 0, this could be an issue.
I also added a unit tests for this change and include the instructions on the test itself on how to generate the yaml file I use for testing.

Eric Christopher and Jorge Gorbe Moya reported some issues with these patches to me off list.
Removing the CodeGenOnly instructions has changed how fneg is handled during fast-isel with sse/sse2. We're now emitting fsub -0.0, x instead
moving to the integer domain(in a GPR), xoring the sign bit, and then moving back to xmm. This is because the fast isel table no longer
contains an entry for (f32/f64 bitcast (i32/i64)) so the target independent fneg code fails. The use of fsub changes the behavior of nan with
respect to -O2 codegen which will always use a pxor. NOTE: We still have a difference with double with -m32 since the move to GPR doesn't work
there. I'll file a separate PR for that and add test cases.
Since removing the CodeGenOnly instructions was fixing PR41619, I'm reverting r358887 which exposed that PR. Though I wouldn't be surprised

[lldb] [lit] Use more readable consts and arrays in register read tests
Replace the constants used for r8/mm/xmm/ymm/zmm tests with something
more readable to ease debugging in case of failures (0x00 0x01 ...).
While at it, put the constants in array and copy them from memory
to simplify inline asm.
The original constants grew out of necessity. The xmm constants were
'weird' because they were intended to be different from mm constants
(as that was necessary to catch NetBSD implementation bug). The ymm
constants were made even weirded to not even partially collide with
other xmm registers (not saying it made sense, just how it was done).
Then, zmm constants were once again designed to avoid accidental
collisions with xmm and ymm constants, and at the same the 16 extra
registers required even more shuffling.
The new constants are meant to be more user-readable, so that a mistake
could be easily spotted. All of xmm, ymm and zmm tests use a sequence
of {0x00 0x01 0x02 ...}, shifted by 1 for every register. This should
provide enough uniquity, and space for future increase in number of
registers. Since mm and r8..r15 are printed as uint64_t rather than
byte-by-byte, they use 0x000102... As a result, on x86 endianness takes
care of making mm different than xmm.
The use of arrays is something I had to learn for zmm write tests. It
avoids having to specify all the input values separately, and makes

These two methods are very similar and various refactorizations need to modify
both similar ways.
One could also just remove GetCompileUnitAtOffset and make
GetCompileUnitContainingDIEOffset to also accept offset of the CU itself
(currently it accepts only DIE offsets after the CU header).
But that would be less safe regarding some internal sanity checking.

[DWARF] Reimplement/simplify DWARFUnit::GetID
Summary:
The implementation of GetID used a relatively complicated algorithm,
which returned some kind of an offset of the unit in some file
(depending on the debug info flavour). The only thing this ID was used
for was to enable subseqent retrieval of the unit from the SymbolFile.
This can be made simpler if we just make the "ID" of the unit an index
into the list of the units belonging to the symbol file. We already
support indexed access to the units, so each unit already has a well
"index" -- this just makes it accessible from within the unit.
To make the distincion between "id" and "offset" clearer (and help catch
any misuses), I also rename DWARFDebugInfo::GetCompileUnit (which
accesses by offset) into DWARFDebugInfo::GetCompileUnitAtOffset.
On its own, this only brings a minor simplification, but it enables
further simplifications in the DIERef class (coming in a follow-up
patch).
