marked as AlwaysInline or ForceInline.
This moves us to what gcc does with -fno-inline. The attribute approach
was discussed to be better than switching to InlineAlways inliner in presence
of LTO.

a subprocess invocation which is pretty significant on Windows. It also
likely saves a bunch of thrashing the host machine needlessly. Finally
it makes the tests much more predictable and less dependent on the host.
For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to
thwart the host detection adding it into the compilation. By runnig CC1
directly we don't have to deal with such oddities.

This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.
To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

These functions have the same constness properties of the normal libm
functions, which allows LLVM to optimise code better in general. There
are also a couple of specific optimisations that only trigger when
these are properly marked.

With the old linkage types removed, set the linkage to external for both
dllimport and dllexport to reflect what's currently supported.

In preparation for making the Win32 triple imply MS ABI mode,
make all tests pass in this mode, or make them use the Itanium
mode explicitly.

Right now clang produces the same DataLayout for all of them, but it could, for
example, add 'n' specifications when the end architecture is given.
No functionality change, this should just make future changes easier to read.

This has no functionality change as clang adds explicit alignment info for
byval arguments. The only difference is that now the clang produced
DataLayout string for AArch64 is identical to the LLVM produced one.
llvm-svn: 197538
This completes the cleanup/refactoring of DataLayout on the clang side. Next
is figuring out the differences between the llvm and clang produced strings
llvm-svn: 197442
These right now just test that the same string is present in two files, but will
become more useful as clang's handling of DataLayout is refactored.
