Guozhi Wei dc5a37bcd2 [InstCombine] Avoid combining the bitcast of a var that is used as both address and result of load instructions
This patch fixes https://llvm.org/bugs/show_bug.cgi?id=27703.

If there is a sequence of one or more load instructions, each loaded value is used as address of later load instruction, bitcast is necessary to change the value type, don't optimize it.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
