foreach isn't needed because make automatically iterates through lists of words when substituting patterns.

060417b0dc Adjust type of int constants that fit in char 
When there is an integral constant like `3` in an expression, it has
type `int` according to the C spec, even though it can be represented
as an `unsigned char`.  Change codegen (`hie_internal` and `typeadjust`)
to treat it as `unsigned char` instead of `int` so that faster,
unsigned operations can be used.

For the test case in #1298, reduces the cycles per iteration from
4311 to 1884.  This is a great improvement, but still much worse than
the 1053 cycles/iter from `c4698df~`, so more work remains to be done.

Further partial fix for #1298 and #1308.

93145246fd Add tests for u8 op s16_const 
Test expressions like `unsigned char x = ...; ... = x / 2;`
These use `int` constants with values representable by
`unsigned int` / `unsigned char`, so using unsigned codegen should
be possible.

Additional tests for #1308.  These are things we want to generate better
code for, so add tests that the behavior doesn't change.

5db74b4b19 Use u16 codegen for u8 x u8 ops 
In g_typeadjust, before we apply the integral promotions, we check if
both types are unsigned char.  If so, we promote to unsigned int, rather
than int, which would be chosen by the standard rules.  This is only a
performance optimization and does not affect correctness, as the flags
returned by g_typeadjust are only used for code generation, and not to
determine types of other expressions containing this one.  All unsigned
char bit-patterns are valid as both int and unsigned int and represent
the same value, so either signed or unsigned int operations can be used.
This special case part is not duplicated by ArithmeticConvert.

Partial fix for #1308.

a686988d0e Add test cases for integral promotion of chars 
Both signed and unsigned chars are promoted to int by C's evaluation
rules.  It is more efficient to use unsigned operations when possible,
however.  These tests will help test the correctness of optimizations
doing that.  See #1308.
