Had a go at implementing checked-multiply differently, but the results worked out slower

Had a go at implementing multiply overflow checking (with a single division, and pre-checks)
...
I also added an occam testcase to help time the different between * and TIMES. But gcc optimises out the loop with TIMES under -O2, and with -O0 there is a factor of four difference.

Fixed all the tests to reflect the new channel-end system, such that they all pass again

Changed pullUp to pull up channel arrays that have direction specifiers applied to the whole array
...
For example, a call like foo(6, cs!) will have cs! pulled up, iff cs was of type CHAN X. If cs was of type CHAN! X, nothing is done (and the needless direction will be removed later on).

Fixed the occam type-checker to work with the new channel-ends, adding direction specifiers where necessary
...
In actual parameters (checking against the formal type), abbreviations (checking against the inferred/specified destination type), and inputs (including inside ALTs) and outputs, direction specifiers are automatically added where needed. With all the other changes, this seems to compile all the occam 2 cgtests, and cgtest87 (which tests directions) as well as Adam's tests so I'm fairly confident that it was the right thing to do.

Fixed the occam and Rain parsers to work with the new channel-ends
...
For now, I have fixed the occam parser so that it allows 1 or more direction specifiers after channel names. So c?? is valid, and should end up being equivalent to c?, but this may need altering later.

Turned the Chan type into a Chan type for full channels and a ChanEnd type for the directed ends

This is the first patch in the series of many that implement this change throughout Tock.
Fixes #70 .

Added support for parsing pragmas, for now just handling the SHARED pragma

Added a map of name attributes (ready for things like PRAGMA SHARED) to the CompState

This should possibly (and could in future) be combined into NameDef and the main csNames map

Made the size of INT vary between 16-,32- and 64-bit platforms
...
Fixes #37 . The change itself was very easy, but the main problem was to then go and change everything in GenerateCTest that had been written using A.Int as a test type.

Added support for the canonicalisation of simple Expressions

Made sure that timer variables are always considered read-only when passed around
...
This fixes a usage checking problem in cgtest08 where the variable would be considered written-to in parallel because it was passed twice in parallel (and not marked as a VAL abbrev)

Stopped the pulling up of fully-resolved array expressions where one of the subscripts is a slice
...
This was causing a problem in the C/C++ backends, where the slice function call was having _sizes appended to it. So now we pull up anything that results in an array, or is a slice.

Made a small change to sort multiplied expressions into order during flattening in the usage checking
...
This makes sure that y*x and x*y are both flattened into x*y, but doesn't yet solve the problem of (x*y)*z vs (y*z)*x

Made sure that the usage checking on plain variables checks anything that doesn't have a replicator in it
...
This means that things like a[0][0] are once again covered by the plain variable check, which means that some more tests now pass.
