Bug Description

Due to (declaim (inline read-byte)) in src/code/load.lisp read-byte becomes inlined, which causes problems:

(with-open-file (stream "/dev/zero" :element-type 'unsigned-byte)
    (declare (file-stream stream))
    (read-byte stream))
The stream #<SB-SYS:FD-STREAM for "file /dev/zero" {A9572D9}> has no suitable method for STREAM-READ-BYTE

I attached a patch, which declaims read-byte notinline at the end of load.lisp

With denormals, the range of negative exponents is different than that of positive ones. I'm fairly certain the patch above will let some infinities through, but slightly larger exponents will result in read-time errors.
