a3818e6f9a Fix a bug in a recent refactor that caused a bunch of programs to miscompile 
or the compiler to crash.

eca86da38c Update Windows version of config.h to note availability of floor/floorf/ceil/ceilf. 
Also pulled Windows-specific modifications to config.h.in to a separate file, so
that changes to it trigger regeneration of config.h (which doesn't happen when the
custom build step for it changes).

76356d9594 Prevent folding of a node with multiple uses if the node already folds a load! 
Here is an example where the load ended up being done twice:

%A = global uint 0

uint %test(uint %B, ubyte %C) {
	%tmp = load uint *%A;
	%X = shl uint %tmp, ubyte %C
	%Cv = sub ubyte 32, %C
	%Y = shr uint %B, ubyte %Cv
	%Z = or uint %Y, %X
	store uint %Z, uint* %A
	ret uint %Z
}

==>

	subl $4, %esp
	movl %ebx, (%esp)
	movl 8(%esp), %edx
	movl A, %eax
	movb 12(%esp), %bl
	movb %bl, %cl
	shldl %cl, %edx, %eax
	movb %bl, %cl
	shldl %cl, %edx, A
	movl (%esp), %ebx
	addl $4, %esp
	ret

7419de89fb Use pattern information to determine whether the use expects this 
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.

aa87e0523d 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
