canonicalize `-bit' and ` bits'

[Matt Kraai <kraai at alumni dot cmu dot edu>]

Howdy,

The documentation seems to have standardized on `32-bit',
`64-bit', `32 bits', and `64 bits'.  The following patch
eliminates the few deviations.  Passed `make info' and `make
dvi', OK to commit?

Matt

	* install.texi: Change ` bit' to `-bit'.
	* md.texi: Change `-bits' to `-bit'.
	* tm.texi:Change `-bits' to ` bits'.

  For the example, loading 32-bit integer or floating-point objects into
! floating-point registers on the Alpha extends them to 64-bits.
  Therefore loading a 64-bit object and then storing it as a 32-bit object
! does not store the low-order 32-bits, as would be the case for a normal
  register.  Therefore, @file{alpha.h} defines @code{CLASS_CANNOT_CHANGE_MODE}
  as @code{FLOAT_REGS} and @code{CLASS_CANNOT_CHANGE_MODE_P} restricts
  mode changes to same-size modes.
