common/sim-fpu.c:2566: warning: assignment discards qualifiers

* config/tc-ppc.c (ppc_elf_cons): Clear frag contents.

sim: drop duplicate break statements in sim-fpu

sim: constify save_data()

The local save_data() function takes a pointer to a buffer and only uses it as
the source to the memcpy() function.  Since it is given const strings, GCC
likes to spit out warnings:
common/sim-trace.c: In function 'trace_prefix':
common/sim-trace.c:697: warning: passing argument 5 of 'save_data' discards
qualifiers from pointer target type

So I've committed this as obvious.

sim: add const markings to env string

The sim-options code assigns a const string to "char *" in decoding the
current environment settings, and only uses it to pass to a printf.  GCC
outputs the warnings:
common/sim-options.c: In function 'standard_option_handler':
