instead of using symlinks
Summary:
In the past I have run into several problems with the way
`test-release.sh` creates all the subproject directories as siblings,
and then uses symlinks to stitch them all together. In some scenarios
this leads to clang not being able to find header files, etc.
This patch changes the script so it directly exports into the correct
target locations for each subproject.

The selection process being split into separate passes, we need generic opcodes
to translate the LLVM IR to target independent code.
This patch adds an opcode for addition: G_ADD.

r100895 landed an llvm-only change to add minix support to googletest.
It did that by putting "defined()" in a macro, which has undefined
behavior. Slightly reshuffle things to remove that undefined behavior.
Also mention in README.LLVM that minix support is a local change.

Adds the corresponding CodeGenInstruction number to each AsmWriterInst. Then write all the operand uniqueing loops using the AsmWriterInst array and indices. Then use the CodeGenInstruction index to fill out the OpCodeInfo array.

is < ``2.0``.
Older versions of psutil (e.g. ``1.2.1`` which is the version shipped with
Ubuntu 14.04) use a different API for retrieving the child processes.
To handle this try the new API first and if that fails try the old API.

This reverts r257221.
This caused several build bot failures
* It looks like some of the tests don't work correctly under Windows
* It looks like the lit per test timeout tests fail
So I'm reverting for now. Once the above failures are fixed running
lit's tests can be enabled again.

directy with ``make check-lit`` and are run as part of
``make check-all``.
In principle we should run lit's testsuite before testing LLVM using lit
so that any problems with lit get discovered before testing LLVM so we
can bail out early. However this implementation (``check-all`` runs all
tests together) seemed simpler and will still report failing lit tests.
Note that the tests and the configured ``lit.site.cfg`` have to be
copied into the build directory to avoid polluting the source tree.

This restores the previous behavior of not including the mnemonic in the classes table for every target that starts instruction lines with the mnemonic. Not only did the table size increase by 1 entry, but the class enum increased in size which caused every class in the array to increase in size. It also grew the size of the function that parsers tokens into classes by a substantial amount.
This adds a new HasMnemonicFirst flag to all AsmParsers. It's set to 1 by default and Hexagon target overrides it to 0.
For the X86 target alone this recovers 324KB of size on the llvm-mc executable.
I believe the current state is still a bad design choice for the Hexagon target as it causes most of the parsing to do a linear search through the entire match table to comparing operands against every instruction until it finds one that works. At least for the other targets we do a binary search based on mnemonic over which to do the linear scan.
