Patch to fix register reuse in mips/crt0.S

[Richard Sandiford]

mips crt0.S calls get_mem_info with a0 set to __memsize, then reuses
this (potentially call-clobbered) value of a0 after the call.

Tested on mips64vr-elf, OK to install?

Richard


	* mips/crt0.S (zerobss): Reload __memsize after call.
