This increases the number of floating point constants that may be emitted
inline, and improves precision for global variable initializers which
can not be emitted in integer form.
This fixes the Olden/Power benchmark with the CBE!!!!

scope instead of function scope. This speeds FP programs quite a bit.

Fairly major change: emit fixed sized allocas in the entry block as a variable,

instead of a variable pointer and an alloca. All accesses to the variable then
use the address-of operator to access it. This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.
