5b8d422524 Remove one of the GCs performed by the --gc-greedy flag. The GC performed by CEntryStub before the first call to C, when --gc-greedy is set, caused a bug in calling API callbacks.

1656dd639a Fix regression caused by the generation of a shift stub during 
snapshot creation in a better way.

Encode whether or not the stub should use sse3 instructions in the
minor key of the stub.  The stubs generated during snapshot creation
will have sse3 disabled, but they will not be found when sse3 is
enabled.  Therefore they will only affect the code generated as part
of the snapshot.

b3f8ce7ce4 Fix regression caused by context creation optimization r2681. 
The issue is that a shift operation is used when creating the
snapshot.  This means that the shift binary operation stub is
generated at snapshot time without sse3 instructions.

The fix is to use division instead.

d87f83c5f8 Fix issue 427: JS tick processor now works out-of-the-box for Chromium on Windows. 
MSVS names '.map' file using only module's name, so both 'a.exe' and 'a.dll' will have 'a.map' file. To distinguish an originating module, we're now checking for image base which is always 00400000 for .exe files, and not 00400000 for .dlls.

Verified that windows-tick-processor can now process logs from Chromium using .map file generated for 'chrome.dll', an that it still works for V8's 'shell.exe'.
