For instance, some recent clang emits this code on x86_64:
0x100002b99 <+57>: callq 0x100002b40 ; step_out_of_here at main.cpp:11
-> 0x100002b9e <+62>: xorl %eax, %eax
0x100002ba0 <+64>: popq %rbp
0x100002ba1 <+65>: retq
and the "xorl %eax, %eax" is attributed to the same line as the callq. Since
step out is supposed to stop just on returning from the function, you can't guarantee
it will end up on the next line. I changed the test to check that we were either
on the call line or on the next line, since either would be right depending on the
debug information.

instruction"
The original patch got reverted as a dependency of cf1c774d6ace59c5adc9ab71b31e .
That patch got relanded so it's also necessary to reland this patch.
Original summary:
After cf1c774d6ace59c5adc9ab71b31e762c1be695b1, Clang seems to generate code
that is more similar to icc/Clang, so we can use the same line numbers for
all compilers in this test.

patches
This reverts commit cf1c774d6ace59c5adc9ab71b31e762c1be695b1.
This change caused several regressions in the gdb test suite - at least
a sample of which was due to line zero instructions making breakpoints
un-lined. I think they're worth investigating/understanding more (&
possibly addressing) before moving forward with this change.
Revert "[FastISel] NFC: Clean up unnecessary bookkeeping"
This reverts commit 3fd39d3694d32efa44242c099e923a7f4d982095.
Revert "[FastISel] NFC: Remove obsolete -fast-isel-sink-local-values option"
This reverts commit a474657e30edccd9e175d92bddeefcfa544751b2.
Revert "Remove static function unused after cf1c774."
This reverts commit dc35368ccf17a7dca0874ace7490cc3836fb063f.
Revert "[lldb] Fix TestThreadStepOut.py after "Flush local value map on every instruction""
This reverts commit 53a14a47ee89dadb8798ca8ed19848f33f4551d5.

Debug info generation & codegen now steps onto the correct line.

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
