Make this more efficient in the following ways:
...
1. Do not statically construct a map when the program starts up, this
is expensive and cannot be optimized. Instead, create a list.
2. Do not insert entries for all function in the module into a hashmap
that lives the full life of the compiler.

2. remove #include
3. Reduce the number of #ifdef's.
4. remove extraneous vertical whitespace.

For PR696:
...
Don't do floor->floorf conversion if floorf is not available. This checks
the compiler's host, not its target, which is incorrect for cross-compilers
Not sure that's important as we don't build many cross-compilers.

When a function takes a variable number of pointer arguments, with a zero
...
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

Basic fix for PR#591; don't convert an fprintf() to an fwrite() if there

is a mismatch in their character type pointers (i.e. fprintf() prints an

We can probably do better than this (such as casting the ubyte to an
sbyte).
