Made some modifications to patch 1 based on suggestions.
Added int_eq_float and ptr_e
The fix for PR87854 outputs an error when a string literal is too large to
compile.
This patch adds dg-error directives to tests affected by the new error message.
Committed to trunk.

The following series of patches reduces the code size of MSP430 programs that
make use of bit shifts.
The MSP430 does not have a native instruction for shifting integers, but in
some cases the native rotate instruction can be substituted. In other cases,
assembly code in libgcc is used to emulate
