a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka) 
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

49bcf33cc7 target-mips: convert bit shuffle ops to TCG 
Bit shuffle operations can be written with very few TCG instructions
(between 5 and 8), so it is worth converting them to TCG.

This code also move all bit shuffle generation code to a separate
function in order to have a cleaner exception code path, that is it
doesn't store back the TCG register to the target register after the
exception, as the TCG register doesn't exist anymore.

492b239197 MIPS: don't free TCG temporary variable twice 
In gen_dmtc0 function, TCG temporary variable t0 is freed at the end of
the function. Variable is freed again in the gen_dmtc0 caller.
I removed the free in gen_dmtc0, to do like in gen_dmfc0, gen_mfc0,
gen_mtc0.
