However, method 'visitBUILD_VECTOR' forgot that a floating point

Fix fragile source-col-map.c test-case.
The test passing was dependent upon your source tree being checked out
in a directory with a long enough path, to cause the diagnostics to

Use stdin instead, so that the error messages consistently use

[lldb] Enable building with Cmake/BUILD_SHARED_LIBS
Summary:
Several changes to fix CMake builds of LLDB with the
BUILD_SHARED_LIBS setting on.
- Force all internal libraries to be built STATIC.
- Add additional library dependencies (pthread, dl,
runtimedyld).
- modify finalisation of SWIG wrapper to symlink the
"lib" dir into python/site-packages, so _lldb.so's
RPATH resolves.
Test Plan: Verified one test case with "dotest.py".

[PM/AA] Start refactoring AliasAnalysis to remove the analysis group and
port it to the new pass manager.
All this does is extract the inner "location" class used by AA into its
own full fledged type. This seems *much* cleaner as MemoryDependence and
soon MemorySSA also use this heavily, and it doesn't make much sense
being inside the AA infrastructure.
This will also make it much easier to break apart the AA infrastructure
into something that stands on its own rather than using the analysis
group design.
There are a few places where this makes APIs not make sense -- they were
taking an AliasAnalysis pointer just to build locations. I'll try to
clean those up in follow-up commits.

[CodeGen][NEON] Emit constants for "immediate" intrinsic arguments.
On ARM/AArch64, we currently always use EmitScalarExpr for the immediate
builtin arguments, instead of directly emitting the constant. When the
overflow sanitizer is enabled, this generates overflow intrinsics
instead of constants, breaking assumptions in various places.
Instead, use the knowledge of "immediates" to directly emit a constant:
- teach the tablegen backend to emit the "immediate" modifiers
- use those modifiers in the NEON CodeGen, on ARM and AArch64.
Fixes PR23517.

make reciprocal estimate code generation more flexible by adding command-line options (3rd try)
The first try (r238051) to land this was reverted due to ExecutionEngine build failure;
that was hopefully addressed by r238788.
The second try (r238842) to land this was reverted due to BUILD_SHARED_LIBS failure;
that was hopefully addressed by r238953.
This patch adds a TargetRecip class for processing many recip codegen possibilities.
The class is intended to handle both command-line options to llc as well
as options passed in from a front-end such as clang with the -mrecip option.
The x86 backend is updated to use the new functionality.
Only -mcpu=btver2 with -ffast-math should see a functional change from this patch.
All other x86 CPUs continue to *not* use reciprocal estimates by default with -ffast-math.

The fix follows the MIPS strategy to add a arch-specific GOTSection

ExecutableWrite class to add the symbols.
It also adds some refactoring on AArch64RelocationPass.cpp based on ARM
