Running the Python style guide checker
[`pep8`](https://pypi.python.org/pypi/pep8) on the Python code headers
in this repository results in the following error being emitted:
$ pep8 utils/build-script
utils/build-script:1:1: E265 block comment should start with '# '
utils/build-script:3:1: E266 too many leading '#' for block comment
utils/build-script:5:1: E266 too many leading '#' for block comment
utils/build-script:6:1: E266 too many leading '#' for block comment
utils/build-script:8:1: E266 too many leading '#' for block comment
utils/build-script:9:1: E266 too many leading '#' for block comment
utils/build-script:11:1: E265 block comment should start with '# '
utils/build-script:11:80: E501 line too long (80 > 79 characters)
The problem is that the code header used in most Python files in the
repository:
1. Do not place a space in between `#` and the rest of the comment.
2. Contains some lines that just barely exceed the recommend length
limit.
In addition, not all code headers in the repository follow the same
template.
This commit moves all Python code headers to the following template:

We were never in this situation. For future reference, there are
two ways to use lit manually:
% lit.py $BUILD/swift*/test-macosx-x86_64/$TESTS
% lit.py --param swift_site_config=$BUILD/swift*/test-macosx-x86_64/lit.site.cfg test/$TESTS
The latter is more verbose, but lets you point at real test files in the
source directory instead of pretending they exist in the build directory.
There are probably still further improvements to be made here.
(P.S. I suggest using -sv if running lit from the command line.)

swift_getGenericMetadata. Mostly ripped off clang's
support for same. I did not feel confident in pulling
over the CMake equivalents, so someone else will need to.
