Altivec style vector loads that ignore the bottom 3 bits of the

(rs6000_debug_addr_mask): New function to print the addr_mask
values if debugging.
(rs6000_debug_print_mode): Call rs6000_debug_addr_mask to print
out addr_mask.
(rs6000_setup_reg_addr_masks): Add support for Altivec style
vector loads that ignore the bottom 3 bits of the address.  Allow
pre-increment and pre-decrement on floating point, even if the
-mupper-regs-{sf,df} options were used.
(rs6000_init_hard_regno_mode_ok): Rework DFmode support if
-mupper-regs-df.  Add support for -mupper-regs-sf.  Rearrange code
placement for direct move support.
(rs6000_option_override_internal): Add checks for -mupper-regs-df
requiring -mvsx, and -mupper-regs-sf requiring -mpower8-vector.
If -mupper-regs, set both -mupper-regs-sf and -mupper-regs-df,
depending on the underlying cpu.
(rs6000_secondary_reload_fail): Add ATTRIBUTE_NORETURN.
(rs6000_secondary_reload_toc_costs): Helper function to identify
costs of a TOC load for secondary reload support.

reload, to determine if a particular memory operation is directly
handled by the hardware, or if it needs support from secondary
reload to create a valid address.
(rs6000_secondary_reload): Rework code, to be clearer.  If the
appropriate -mupper-regs-{sf,df} is used, use FPR registers to
reload scalar values, since the FPR registers have D-form
addressing. Move most of the code handling memory to the function
rs6000_secondary_reload_memory, and use the reg_addr structure to
determine what type of address modes are supported.  Print more
debug information if -mdebug=addr.

into a single place.  Prefer using FLOAT_REGS for scalar floating
point.
(rs6000_secondary_reload_class): Use a FPR register to move a
value from an Altivec register to a GPR, and vice versa.  Move VSX
handling above traditional floating point.

* config/rs6000/rs6000.md (mov<mode>_hardfloat, FMOVE32 case):

constants to the constant pool before register allocation.
Normally constants are put into the pool immediately, but
-ffast-math delays putting them into the constant pool for the
