Subject: CMake: set stack size for MSVC in just one place
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=4d1a9256752048f34c6091cc145fce9f89d20985

CMake: set stack size for MSVC in just one place

After r192904, Reid pointed out he thought we already set the stack
size for MSVC. Turns out we did, but it didn't seem to work.

This commit sets the stack size in a single place, using
CMAKE_EXE_LINKER_FLAGS because that seems to be the way that works
best.
