[PATCH 0/5] Drop float32/float64 accessors used by gdbstub code

[Peter Maydell]

We used to make a distinction between 'float64'/'float32' types and
the 'uint64_t'/'uint32_t' types, requiring special conversion
operations to go between them.  We've now dropped this distinction as
unnecessary, and the 'float*' types remain primarily for
documentation purposes when used in places like the function
prototypes of TCG helper functions.

This means that there's no need for special gdb_get_float64() and
gdb_get_float32() functions to write float64 or float32 values to the
GDB protocol buffer; we can just use gdb_get_reg64() and
gdb_get_reg32().

Similarly, for reading a value out of the GDB buffer into a float64
or float32 we can use ldq_p() or ldl_p() and need not use ldfq_p()
or ldfl_p().

This patchseries drops the use of the gdb_get_float* and ldf*
functions from the three targets that were using them, and then
removes the now-unused functions from gdbstub.h and bswap.h.
