Don't write to EXRAM if it doesn't exist.

Previously, if a gamecube game wrote to an EXRAM address, dolphin would
segfault.
Panic on invalid reads/writes for non-mmu games.

Previously it would fall through to the mmu code path, and raise a dsi
exception, which it would never check for, so it would continue
executing code silently.
When loading the map file for a DOL/ELF file, extract only the filename from the DOL/ELF'S path
Parse input as hex instead of decimal to match display values in the debugger's register view

DolphinWX: Fix case where the debugger would crash on hiding a pane.

These ID values would clash with the window parent IDs of all the actual debugger panes (they are in the 350 range as well).

For example, attempting to show and then close the memory window would cause an assertion, because it would attempt to destroy the text control for searching through memory, rather than destroying the actual parent window it's attached to.

These IDs are only used locally, so their value doesn't matter.
JIT: a small optimization for subfex and friends
