Inline assembly [hn]to[nh][sl] functions used xchgb %h1,%b1 instead of the
...
faster (on the i486 & i586) rorw $8, %w1. The inline assembly for GCC 1.X
already used rorw. Using rorw is one byte longer, but we wouldn't be
inlining at all if we weren't optimizing for speed.

fix from Thomas Eberhardt <thomas@mathematik.uni-Bremen.de>:
...
byte swap macros used a variable "X" internally, which would get
screwed up if user programs #defined "X". change uses of X to __x.

FPU control word of 0x137f doesn't work well in "real" world applications
...
so I've changed it to 0x127f. 64 bit precision causes errors in paranoia
and our math library, changing to 53 bit precision solves these problems.
I've been told that long double support in Gcc 2.5 requires 64 bit mode,
so a comprehensive FP strategy (compiler, library, FPU, emulator) will
have to be addressed in the future.

also, delete r_fs and r_gs; looking at the code and comments

bump MAXSSIZ back down to 8M (from 256M, where charles put it).
...
execve() currently allocated MAXSSIZ of address space (AND PAGE TABLES)
for the stack. until that's changed, and the stack-handling code is
updated to match, MAXSSIZ==256M will make execve() significantly slower
than MAXSSIZ==8M.
