e211e3f64d Issue #339 - Fix fast path in make-string 
We need to ensure the code point buffer only contains a single byte in order to use the fast path for string creation. For example if there is one code point that is 2 bytes large we need to use the slow path.

f3c83e42a4 Optimized versions of (map) and (for-each) 
These versions are optimized for when the function is being called with two list arguments.

ec25eddc28 Issue #331 - Prevent syntax error during eval 
Prevent an unquoted symbol from throwing a syntax error when evaluating a define-record-type form. Note there are still other issues with creating a record type in the interpreter at this time.

12d6cbce5a Use explicit if's instead of memv for case 
Theory is the generated code can make better use of the processor cached when using explicit if statements than aggregating over a list via memv, since pairs in the list can be located anywhere across memory.

0f0beb024c Do not use vector-set when creating record types 
This improves performance as mutations force the GC to do more work.

d731f92e7d read-string: return EOF if nothing can be read 
R7RS states that there's three possible scenarios for read-string:

- More characters can be read than asked for (return string)
- Less characters can be read than asked for (return string)
- No characters can be read (return EOF)

This commit ensures the last scenario works as intended.
