Runtime should use LINK_LIBRARIES to link to ICU, since it is a static
archive, and we need this link dependency to be propagated to the
libswiftSwiftCore library. I have no idea why it linked correctly
worked before.

The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.
See stdlib/{public,internal,private}/README.txt for more information.

disabling the standard library
In almost all cases, CMake will happily operate on undefined variables,
treating them as empty, but for some reason list(REMOVE_ITEM) is an
exception.

The reason why this is necessary is that I need to update parts of the runtime
for +0 self. I am going to use a -D flag to do this implying I need the build
system's help. Since I already have the flag I am also going to wire up the
emission of +0 self code from the compiler to be triggered off this as well.
It is of course disabled by default.

Now if you want to get these dynamic metrics from the runtime all you
need to do is:
1. Configure Swift with -DSWIFT_RUNTIME_ENABLE_DTRACE=YES
2. Run your routine with the command:
sudo dtrace -s ./utils/runtime_statistics.d -c "$MY_COMMAND_LINE"
After your app finishes running, it will dump out the counts. This is a
much more efficient and low maintenance way to get such statistics than
custom instrumenting the code.
Nothing is changed if -DSWIFT_RUNTIME_ENABLE_DTRACE is not set.

This adds support to build-script and cmake scripts for cross-compiling the host tools in addition to stdlib.
To cross-compile, build-script-impl now accepts --cross-compile-tools-deployment-targets with a space separated list of targets to cross compile host Swift tools for.
For example: $ build-script ...other-args... -- --cross-compile-tools-deployment-targets="iphoneos-arm64 iphoneos-armv7".
When installing cross-compiled tools, it now also merges and runs lipo to produce fat binaries by merging the cross-compiled target architectures.

The SLPVectorizer is now faster (rdar://problem/19430955): it needs 2.5% of stdlib compile time.

This shaves around 5 seconds off the stdlib build if you're using a
release/no-assert LLVM (so around 12.5% of total time if you're also
using a release/no-assert swift, or around 4% of total time if you're
using a debug/assert swift).
The underlying LLVM issue is tracked by rdar://problem/19430955.
I saw no significant reproducible performance loss due to this change.

Often times one wants to pass certain flags to swift when building
specific libraries and not others. This has in the past required
manually modifying the cmake system. This new option allows one to use
string regexps based on the module_name of a library to enable and
disable various flags. The way this works is you pass the following into
build-script:
--extra-swift-options="${REGEX1};${FLAGS1_WITH_SEMICOLONS_ESCAPED}"
--extra-swift-options="${REGEX2};${FLAGS2_WITH_SEMICOLONS_ESCAPED}"
--extra-swift-options="${REGEX3};${FLAGS3_WITH_SEMICOLONS_ESCAPED}"
--extra-swift-options="${REGEX4};${FLAGS4_WITH_SEMICOLONS_ESCAPED}"
--extra-swift-options="${REGEX5};${FLAGS5_WITH_SEMICOLONS_ESCAPED}"
Every library that matches REGEPN will have FLAGSN_... appended to their
swift flags. For instance if I did the following:
build-script --extra-swift-options="Swift;-Xfrontend\;-sil-print-pass-name" --extra-swift-options='^Swift$;-Xllvm\;-debug-only=sil-arc-opts" ...
CMake will output the following:
-- Matched 'Swift' to module 'Swift'. Compiling Swift with special flags: -Xfrontend;-sil-print-pass-name
-- Matched '^Swift$' to module 'Swift'. Compiling Swift with special flags: -Xllvm;-debug-only=sil-arc-opts
-- Matched 'Swift' to module 'SwiftExperimental'. Compiling SwiftExperimental with special flags: -Xfrontend;-sil-print-pass-name
-- Matched 'Swift' to module 'SwiftStructures'. Compiling SwiftStructures with special flags: -Xfrontend;-sil-print-pass-name
-- Matched 'Swift' to module 'SwiftStructuresGraphBFS'. Compiling SwiftStructuresGraphBFS with special flags: -Xfrontend;-sil-print-pass-name
stating which regexp was matched, the module it was matched to and the
added flags. This ensures that one only gets matches for what one wants.

This worked in standalone build by creating a directory that never got used but it failed in a non-standalone build.
Fix tracked with Dmitri's help.
