The inbounds keyword isn't relevant to overindexing of

static array types. Thanks to Duncan for pointing this out!

add the ability for TargetData to return information about legal integer
...
datatypes on a given CPU. This is intended to allow instcombine and other
transformations to avoid converting big sequences of operations to an
inconvenient width, and will help clean up after SRoA. See also "Adding
legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.
Comments welcome.

indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it

Make blockaddress(@func, null) be valid, and make 'deleting a basic
...
block with a blockaddress still referring to it' replace the invalid
blockaddress with a new blockaddress(@func, null) instead of a
inttoptr(1).
This changes the bitcode encoding format, and still needs codegen
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

Move the integer type out of 'derived' and into 'primitive'. This permits us

to explain that derived types are all composed of other types, which primitive
types aren't. Without moving integer out of derived, this wouldn't be true.
Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to
#t_integer (a holdover from when it was a bool type I suppose).
