Implement Lambda Conversion Operators for All CCs for MSVC.
As described here:
https://devblogs.microsoft.com/oldnewthing/
20150220-00/?p=44623
In order to allow Lambdas to be used with traditional Win32 APIs, they
emit a conversion function for (what Raymond Chen claims is all) a
number of the calling conventions. Through experimentation, we
discovered that the list isn't quite 'all'.
This patch implements this by taking the list of conversions that MSVC
emits (across 'all' architectures, I don't see any CCs on ARM), then
emits them if they are supported by the current target.
However, we also add 3 other options (which may be duplicates):
free-function, member-function, and operator() calling conventions. We
do this because we have an extension where we generate both free and
member for these cases so th at people specifying a calling convention
on the lambda will have the expected behavior when specifying one of
those two.
MSVC doesn't seem to permit specifying calling-convention on lambdas,
but we do, so we need to make sure those are emitted as well. We do this
so that clang-only conventions are supported if the user specifies them.

[clang] Add an option for hiding line numbers in diagnostics
Clang offers a `-f[no]-show-column` flag for hiding the column numbers when
printing diagnostics but there is no option for doing the same with line
numbers.
In LLDB having this option would be useful, as LLDB sometimes only knows the
file name for a SourceLocation and just assigns it the dummy line/column `1:1`.
These fake line/column numbers are confusing to the user and LLDB should be able
to tell clang to hide *both* the column and the line number when rendering text
diagnostics.
This patch adds a flag for also hiding the line numbers. It's not exposed via
the command line flags as it's most likely not very useful for any user and can
lead to ambiguous output when the user decides to only hide either the line or
the column number (where `file:1: ...` could now refer to both line 1 or column
1 depending on the compiler flags). LLDB can just access the DiagnosticOptions
directly when constructing its internal Clang instance.
The effect doesn't apply to Vi/MSVC style diagnostics because it's not defined
how these diagnostic styles would show an omitted line number (MSVC doesn't have
such an option and Vi's line mode is theory only supporting line numbers if I
understand it correctly).

Reland [lldb] Explicitly use the configuration architecture when building test executables
This originally broke the TestQuoting which explicitly called buildDefault
instead of calling build() and marking the test as no_debug_info_test.
TestQuoting has been rewritten by now and is using `build`, so this should now
pass on all platforms.
Original summary:
The Darwin builder currently assumes in `getArchCFlags` that the passed `arch`
value is an actual string it can string.join with vendor/os/version/env strings:
```
triple = '-'.join([arch, vendor, os, version, env])
```
However this is not true for most tests as we just pass down the `arch=None`
default value from `TestBase.build`. This causes that if we actually end up in
this function we just error out when concatenating `None` with the other actual
strings of vendor/os/version/env. What we should do instead is check that if
there is no test-specific architecture that we fall back to the configuration's
architecture value.
It seems we already worked around this in `builder.getArchSpec` by explicitly
falling back to the architecture specified in the configuration.
This patch just moves this fallback logic to the top `build` function so that it
affects all functions called from `TestBase.build`.

[X86] Enable shrink-wrapping for no-frame-pointer non-nounwind functions on platforms not using compact unwind
The current compact unwind scheme does not work when the prologue is not at the
start (the instructions before the prologue cannot be described). (Technically
this is fixable, but it requires multiple compact unwind descriptors for one
function.)
rL255175 chose to not perform shrink-wrapping for no-frame-pointer functions not
marked as nounwind to work around PR25614. This is overly limited, as platforms
not supporting compact unwind (all non-Darwin) does not need the workaround.

The crashlog script was hacking around that by setting the lldb.debugger
to a newly created debugger instance when running outside of the script
interpreter, which works fine until lldb creates a script interpreter
instance under the hood and clears the variables. This was resulting in
an AttributeError when invoking the script directly (from outside of

[MemorySSA] Use provided memory location even if instruction is call
If getClobberingMemoryAccess() is called with an explicit
MemoryLocation, but the starting access happens to be a call, the

similar happens if the starting access is a load with a MemoryDef.
Change the implementation to not set Q.Inst in the first place if
we want to perform a MemoryLocation-based query, to make sure it
can't be turned into an Instruction-based query along the way...
Additionally, remove the special handling that lifetime.start
intrinsics currently get. They simply report NoAlias for clobbers
between lifetime.start and other calls, but that's obviously not
right if the other call is something like a memset or memcpy. The
