Mark symbols as constant
Aarch64_legitimate_constant_p currently returns false for symbols,
eventhough they are always valid constants. This means LOSYM isn't
CSEd correctly. If we return true CSE works better, resulting in
smaller/faster code (0.3% smaller code on SPEC2006). Avoid this
for TLS symbols since their sequence is complex.
gcc/
* config/aarch64/aarch64.c (aarch64_legitimate_constant_p):
Return true for non-tls symbols.
