40d2fd65b0 Add OrderedAnd patterns, and use them in ? patterns. 
This guarantees that patterns like (? pred pat) will
always check `pred` before matching any of `pat`.
However, `and` patterns are not required to match left-
to-right.

f42cc6f14a Fixed major performance issue with matrix arithmetic; please merge to 5.3.2 
The fix consists of three parts:

1. Rewriting `inline-matrix*'. The material change here is that the
   expansion now contains only direct applications of `+' and `*'.
   TR's optimizer replaces them with `unsafe-fx+' and `unsafe-fx*',
   which keeps intermediate flonum values from being boxed.

2. Making the types of all functions that operate on (Matrix Number)
   values more precise. Now TR can prove that matrix operations preserve
   inexactness. For example, matrix-conjugate : (Matrix Flonum) ->
   (Matrix Flonum) and three other cases for Real, Float-Complex, and
   Number.

3. Changing the return types of some functions that used to return
   things like (Matrix (U A 0)). Now that we worry about preserving
   inexactness, we can't have `matrix-upper-triangle' always return a
   matrix that contains exact zeros. It now accepts an optional `zero'
   argument of type A.

a0f910c3dc more adjustments to the c:x;r;a keystroke 
The goal is to better handle situations like this one:

╔═══╗
║ - ║
╚═══╝

where the hyphen should not change.

1744a78738 mach-o: fix problems related to code signing 
Strip any code signing when generating an executable from
Racket or GRacket. Also, place the __LINKEDIT segment in
virtual memory after the __PLTSCHEME segment, so that
the in-memory layout order matches the file layout order,
which in turn makes the code-signing tool's update of the
__LINKEDIT segment's size not create a virtual-memory
overlap with __PLTSCHEME.

* Narrowed type of `submatrix' to only sensible argument types

* `matrix-invertible?' now returns #f when given a non-square matrix
  instead of raising an error

* Allowed `matrix-diagonal' to operate on non-square matrices

f40ad2ca9d `math/matrix' fixes; please merge to 5.3.2. 
* Fixed type of `matrix-expt'

* Made matrix functions respect `array-strictness' parameter (mostly
  wrapping functions with `parameterize' and return values with
  `array-default-strictness'; reindentation makes changes look larger)

* Added strictness tests
