x86emitter: Purge empty file sse_helpers.h.

Code was removed in
https://github.com/PCSX2/pcsx2/commit/60a9463e7ad3c8936eae1aad688cf72e6c734159
Right now it's useless.
Update VS/cmake project files to remove any mentions of the file as
well.

gsdx-gui: Add hotkey nametags to some options that have hotkey support already.

Lilypad: Don't toggle width and heigh for Inputs window with Show/hide Special Inputs button.

Use a fixed size instead. It will avoid DPI scaling issues.
Also adjust the Special Inputs buttons height position so that the
window height remains a reasonable size.

Lilypad: Partially revert #2832

DPI scaling doesn't work for the window resize so it made things worse.
Maybe once that is fixed this code can be reverted back again.

gsdx device: use same target for fxaa/shaderboost/shaderfx

It avoid to waste VRAM memory

gsdx device: use generic resize texture function

V2: add missing size for merge and interlace

onepad/onepad legacy: Remove Windows placeholder dirs.

They are useless.

spu2-x-gui: Reduce window height.

Should help low res monitors.

gsdx-gui: Adjust some button positioning and window width.

"Symmetry"

gsdx: Reuse same selected renderer image/banner for ps1 emu compatibility as ps2.

There's no need to have duplicate images that basically do the same
thing. Update the gui to reflect latest changes and use the same images
on both. It will reduce plugin size.
Remove old images and update VS project files.

gsdx: Adjust/cleanup ini options.

Opencl device, Alpha, Alpha stencil are windows only options so no need
to clutter ini on linux with useless stuff.

gsdx: Cleanup/update Wild Arms offset hack.

Don't use integer for the variable, option has only on and off states.
Use member variable names and adjust some checks.

gsdx: Move GSTexturecache files from Common to HW renderer.

GSdx: Adjust Burnout crc hacks to work on multiplayer mode as well.

Yellow stripes crc hack.
Note: Only Takedown was tested but other games should work as well.

lilypad: Some tweaks and fixes.

Hide all ps1 emu options instead of disable. Some options still got
enabled when they shouldn't have so just hide everything. This way we
avoid adding extra code, plus the gui looks cleaner.

Disable ini read/write for Analog ps1 mode, the feature was accidentaly
enabled for pcsx2. By looking at the code it should only be enabled for
ps1 combatibility mode. Also hide the option for pcsx2 as well.

Move around some of the hacks and advanced options to reflect the recent
changes.

gsdx-egl: Also do the same for egl pointer logs.

gsdx-ogl: Enable function pointer support logs only when "debug_opengl" is enabled in the ini.

They are mostly for debugging driver issues so regular users don't
actually need to see them most of the time.

[skip ci] gsdumpgui: Auto select first GSdx dll on the list upon program launch.

[skip ci] gsdumpgui: Allow to open ini file even when no gsdx dll is selected.

ini file is already shared between dlls (previous commit) so there's no
need for verification anymore.

[skip ci] gsdumpgui: Update code to share only one gsdx config for all dlls.
